Zenity demonstrated a 'prompt mine' against Salesforce Einstein. An attacker writes malicious instructions into a legitimate CRM intake path — Email-to-Case or Web-to-Case lets external users create support cases — splitting the payload across several case records to work around field length limits. The payload then lies dormant until an employee asks a common follow-up question that causes Einstein to retrieve the poisoned records into context; Zenity notes Einstein can include a malicious record in context even when the user interface renders only the first few cases, so the employee never sees the trigger. The injected instructions direct the agent to query contact IDs and repeatedly invoke UpdateCustomerContact, corrupting customer contact records. Because the harm is a committed write rather than a disclosure, recovery requires identifying which records were touched, restoring trusted values, and reconciling the incident-scoped set of agent-issued CRM writes before write autonomy is re-enabled.
ASSESSED SYSTEM
A Salesforce Einstein / Agentforce CRM agent configuration as demonstrated by Zenity in July 2026: retrieval over Case records that are writable from the public Email-to-Case and Web-to-Case intake paths, combined with an enabled CRM write action (UpdateCustomerContact) available to the agent in the same session as read-only user questions.
OUT OF SCOPE
The Salesforce platform's non-AI security surface; Agentforce topics and actions other than the demonstrated case-retrieval and contact-update path; the attacker's infrastructure; tenants that have not enabled CRM write actions for the agent, whose configuration differs materially; and any hardening Salesforce or its customers have applied since disclosure. This is a point-in-time assessment of the demonstrated configuration, not a rating of the Salesforce product.
Architecture: Agentic / MCP System (decision tree Q2) — Q1 is NO: one agent, no inter-agent messaging evidenced. Q2 is YES: from a single ordinary user question the agent planned and executed a multi-step workflow — retrieve related Case records, query contact IDs, then repeatedly invoke the UpdateCustomerContact tool — invoking CRM write connectors without explicit human approval for each action. Task state persisted across the retrieval and mutation steps, which is what allowed a delayed payload planted days earlier to govern a later session. Tier 2: Tier 2 Consumer: although the agent's operators are authenticated employees, its retrieval corpus is writable by anonymous external parties through Email-to-Case and Web-to-Case, and the realised harm — corruption of customer contact records — lands directly on identifiable individuals outside the organisation.
Documented attack or failure path
- An external party uses the legitimate Email-to-Case or Web-to-Case intake path to create support cases containing malicious instruction text.
- The payload is split across several cases to work around field length limits, and is written in a form that stays dormant until a common follow-up question is asked.
- An employee asks an ordinary question about a case; Einstein retrieves related case records into the agent context, including the poisoned records — which can enter context even when the user interface renders only the first few cases, so the injection is invisible to the employee.
- Under the injected instructions the agent queries contact IDs, converting a read-only question into a plan that targets a set of CRM records.
- The agent repeatedly invokes the UpdateCustomerContact write action; no independent validator checks the plan, record count, purpose or approval evidence, and no containment decision sits in front of the tool dispatcher.
- Customer contact records are corrupted; recovery requires record-level change history, trusted snapshots and reconciliation of every agent-issued write against authoritative record state.
Observed controls and bounded outcomes
Positive credit is given only where the record directly demonstrates a control operating. Recommended or merely presumed controls receive no positive scoring credit.
- Platform-level field validation constrained the payload: field length limits forced the attacker to split the injection across several case records rather than planting it in one, which is a real (if incidental) structural constraint on the poisoning channel.
- The agent operated within Salesforce's existing CRM permission model; the write it performed was one the configured action inventory permitted, so no platform privilege boundary was broken and no data outside the tenant was reached.
- The harm was confined to record content that Salesforce's change-history and snapshot facilities can be used to identify and restore, so a recovery path existed — the brief's remediation guidance assumes record-level change history and trusted snapshots are obtainable.
Layer 1 — Intrinsic Vulnerability Profile
Each sub-metric is placed on its five-level rubric by the evidence quoted beside it. Missing applicable evidence remains unknown. The displayed midpoint and interval are scenario values, not inferred control performance.
| Sub-metric | Score | Rubric basis | Evidence |
|---|---|---|---|
| Robustness (Ro) — scenario interval 0.14–0.59 (midpoint 0.36), Tier 2 MVT 0.50 indeterminate | |||
| Ro-1Adversarial Input Resistance | 0.25w 0.30 | 0.25: product-level input handling resists naive single-field injection but failed against a moderately engineered multi-record payload with a delayed trigger, and the resulting policy-bypass and unsafe-tool-invocation rate on the demonstrated path was total. No ASR measurement is published, so the placement rests on the qualitative criterion. | Indirect prompt injection delivered through retrieved case text controlled the agent end to end. The payload was engineered rather than naive — split across multiple records to defeat field length limits, and written with a delayed trigger so it activated only when a user asked a common follow-up question — and nothing in the retrieval or context-assembly path detected cross-record delimiters, hidden policy language or delayed trigger wording. The brief's remediation list asks defenders to scan case fields entering AI context for exactly these patterns, indicating no such scanning was in force.source: researcher |
| Ro-4Poisoning Attack Resistance | 0.25w 0.25 | 0.25: basic validation such as format and length checks exists, but there is no adversarial screening of the ingestion channel, and poisoning of the retrieval corpus succeeded with limited effort, matching the anchor's description of poisoning succeeding against RAG or memory content. | This is retrieval-corpus poisoning through a sanctioned channel: Email-to-Case and Web-to-Case let external users write records that later enter the agent's retrieval context, with no provenance labelling, source-trust rating, adversarial screening or quarantine applied to externally authored case text before it reaches the model. Structural validation did apply — field limits shaped the payload — but content screening did not.source: researcher |
| Fairness (Fa) — scenario interval 0.00–1.00 (midpoint 0.50), Tier 2 MVT 0.55 indeterminate | |||
| Transparency (Tr) — scenario interval 0.00–1.00 (midpoint 0.50), Tier 2 MVT 0.50 indeterminate | |||
| Privacy (Pr) — scenario interval 0.00–1.00 (midpoint 0.50), Tier 2 MVT 0.55 indeterminate | |||
| Containment (Cn) — scenario interval 0.07–0.67 (midpoint 0.37), Tier 2 MVT 0.55 indeterminate | |||
| Cn-1Scope Enforcement | 0.25w 0.12 | 0.25: boundaries exist at the platform permission layer but are enforced inconsistently at the task layer — a scope derived from the session rather than from the trusted user request meant simple content manipulation exceeded the intended read-only scope. | A read-only question about a case carried contact-update capability into the same session, so retrieved text was able to move the agent from reading to mutating records. The action inventory available to the agent was not derived from the user's trusted request; the brief's first remediation is to inventory every Einstein or Agentforce action that can write, update, delete, export or send CRM data and bind each to an authority envelope, separating reading and explaining a case from modifying contacts.source: researcher |
| Cn-2Escalation Prevention | 0.25w 0.16 | 0.25: role checks exist but are vulnerable to role confusion via prompt injection and delegated tool misuse — untrusted retrieved content spoke with the operator's authority, which is the anchor's exact condition. | Text authored by an anonymous external party inside a support case obtained the authority of an authenticated employee's agent session and used it to issue CRM writes the employee never requested. No policy engine denied write actions whose justification came from retrieved customer case text rather than from an authorised user, workflow or admin-approved rule.source: researcher |
| Cn-6Action Reversibility Classification Rate | 0.00w 0.12 | 0.00: no reversibility classification is performed before execution and automated actions execute without gating, ARCR = 0 for the demonstrated action space. There is no evidence of even ad-hoc thresholds (record count, monetary value, blast radius) that would lift this to 0.25. | The central finding of the case. UpdateCustomerContact was invoked repeatedly against a set of records with no pre-execution reversibility classification and no gate of any kind: no independent validator verified the plan, record count, purpose or approval evidence; no fail-closed containment decision sat immediately before the tool dispatcher; and no step-up approval was required for bulk or repeated writes. A bulk CRM mutation is bounded-irreversible at minimum — recovery needs change history, trusted snapshots and reconciliation of every agent-issued write — and it executed ungated.source: researcher |
Unknown, not N/A: 18 applicable sub-metrics lack admissible public evidence. The lower, midpoint, and upper scenarios evaluate each at 0.00, 0.50, and 1.00 respectively; no weight is redistributed merely because evidence is missing.
Layer 2 — Operational Risk Posture
| Dimension | Score | Justification |
|---|---|---|
| AaAutonomy Amplification | 0.90w 0.25 | Just below the full-autonomy anchor. Within the assessed configuration the agent modified customer records of record repeatedly, without human confirmation for any individual write and without any exception threshold escalating bulk updates — which is the 1.00 anchor's 'can call tools, modify data ... independently'. Held at 0.90 rather than 1.00 because the agent does not operate as a standing unattended process: a human initiated the session and was nominally present, even though the writes themselves were neither shown to nor approved by that human. elevated |
| AsAttack Surface Exposure | 0.85w 0.35 | Between the 0.75 and 1.00 anchors. External data ingestion is unambiguous and matches 0.75 exactly: an internet-facing intake path (Email-to-Case, Web-to-Case) feeds partially trusted content into the retrieval corpus. Raised above 0.75 because the assessed configuration combines that untrusted retrieval with a CRM write-tool integration in the same session, which is the additional condition the 1.00 anchor names. Held below 1.00 because the agent interface itself is reached only by authenticated internal users and no communication with external agents is evidenced. elevated |
| CpCascade Potential | 1.00w 0.20 | No verified System Dependency Graph is published, but the demonstrated chain triggers the 1.00 anchor independently. An ungated path ran from externally authored case text (an entry-exposed L1/L2 origin) through the planner to a P3 write-external, irreversible-capable node — the UpdateCustomerContact action mutating the customer system of record — and executed there repeatedly. The spec's 1.00 condition is met literally: an ungated path reaching a P3 node and a bounded-irreversible action node, with no gate anywhere on the path to claim a containment block rate against.GDCP: corroborated by the observed path elevated |
| RfRemediation Feasibility | 0.25w 0.20 | Configuration and deployment-layer fixes, days to implement: remove or gate the write action, bind each action to an authority envelope derived from the trusted user request, insert an independent validation and approval gate before bulk updates, and place a fail-closed containment decision in front of the tool dispatcher. Not 0.00, because the fix is not a single deterministic patch — it also requires a recovery programme (identify affected records, restore trusted values, reconcile every agent-issued write) before write autonomy is re-enabled, and the underlying injection susceptibility is bounded rather than eliminated by these gates. |
Nelevated = 3 (dimensions strictly above 0.75) → CRM = 1.35.
Compound Risk Alert. Two or more dimensions are simultaneously elevated (spec 3.2.2); architectural decomposition is recommended before deployment.
Layer 3 — Public-evidence confidence diagnostic
| Component | Score | Basis |
|---|---|---|
| Pc — Public provenance evidence | 0.25 | Minimal provenance record. The platform, the intake paths and the action name are documented, and the vendor and deployment owner are known, but nothing in the available evidence documents the assessed tenant's action inventory, prompt lineage, retrieval scope policy, guardrail configuration or identity policy, and no AIBOM or equivalent exists. That is the 0.25 anchor: named product, vendor and owner with high-level description only, no cryptographic or review evidence. |
| Ec — Public evaluation coverage | 0.21 | coverage 0.22 (5 of 23 applicable sub-metrics) × independence 1.00 × fidelity 0.95. No Full, Standard, or Lite pathway is claimed for a retrospective article. |
| Tf — Public-evidence freshness | 0.00 | Evidence dated 2025-08-14; age 364 days on the workpaper reference date. Components: T_behavior 0.00 · T_containment 0.00 · T_calendar 0.06 · C_event 0.35 · C_monitor 0.65 · C_evidence 0.85. Binding term: T_behavior. dt_days = 364, measured from the primary public disclosure dated 2025-08-14 to the 2026-08-13 evidence reference date; the AIDEFEND brief republished the analysis on 2026-07-07. agentic = true: an Agentic-class deployment whose action inventory and permission scopes are administrator-mutable at runtime, so the containment staleness floor applies. baw = true on the closed-feedback-loop checklist item: the agent's own CRM writes become record state that the same agent later retrieves as context, so its output feeds its own future decision path — which is precisely the mechanism a delayed prompt mine exploits. C_event = 0.35: a major behavioural event — a confirmed critical-invariant violation in which the agent performed unauthorised bulk mutation of records of record. C_monitor = 0.65: no session ledger or intent-drift detection connected the retrieval of suspicious case text with the later shift into CRM mutation, so the detection gap is structural in the assessed configuration rather than a coverage percentage. C_evidence = 0.85: the action-authorisation gap was open at the assessed point in time, and the brief explicitly conditions re-enabling write autonomy on closing it. Public-evidence coverage is reported directly; no AITBM assessment pathway is assigned. |
Public-evidence ACI = (Pc × Ec × Tf)1/3 = 0.02 — diagnostic status: Invalid as assessment-of-record evidence. It describes the evidence available to this case study, not the assurance of the underlying system, and is not inserted into the normalized-assurance scenario ERS.

AIDEFEND defences → AITBM sub-metrics
Identifiers are quoted as they appear on the AIDEFEND in Action brief (retrieved 2026-08-13); the sub-metric mapping is AITBM's own, from the specification's AIDEFEND tables reconciled at catalogue data version 2026.08.05. AIDEFEND renumbers identifiers between releases, so the data version travels with every mapping and neither side's IDs should be cited without one. A mapping identifies a possible evidence route; a recommendation does not prove that the control was implemented or effective and receives no scoring credit by itself.
| Technique | Defence | Priority | Evidences |
|---|---|---|---|
| AID-H-018.004 | Intent-Based Dynamic Capability ScopingDirect owner of the Cn-1 finding: a user asking what a case is about should not grant contact-update capability, and the dispatcher should derive a signed scope from the trusted user request rather than from the session. | Very High | Cn-1 Cn-6 Cn-7 |
| AID-H-018.003 | High-Impact Independent Validation & Approval GateDirect owner of the Cn-6 = 0.00 finding. A separate validator verifying plan, record count, purpose and approval evidence before UpdateCustomerContact runs is the control whose absence makes ARCR zero for this action space. | Very High | Cn-1 Cn-6 Cn-7 |
| AID-I-003.004 | High-Risk Agent Action ContainmentParent AID-I-003 maps directly to Cn-5 and Cn-6 in the reconciled AIDEFEND dataVersion 2026.08.05 crosswalk. Substantively it is the fail-closed decision point immediately before the CRM tool dispatcher that Cn-6 measures: if the write is inconsistent with the read-only question, or the containment service is unavailable, block, re-plan read-only, defer, or require fresh human approval. | Very High | Cn-5 Cn-6 Cn-7 |
| AID-H-018.002 | Policy-Based Access ControlDenies write actions whose justification originates in retrieved customer case text rather than in an authorised user, workflow or admin-approved rule — the Cn-2 escalation condition expressed as a policy decision. | High | Cn-1 Cn-6 Cn-7 |
| AID-H-017.003 | Decoupled Plan-Then-Execute ArchitectureParent AID-H-017 (Secure Agent Architecture) maps to Cn-5. Plan validation catches the mismatch between a read-only follow-up question and a proposed plan that mutates many CRM records, giving the chain a checkpoint before side effects. | High | Cn-5 Cn-7 |
| AID-H-017.007 | Dual-LLM Isolation PatternA quarantined parser reads raw case records and passes only typed, safe summaries to the privileged agent, so the component that can call CRM tools never sees raw public case text as instructions. Structural answer to the Ro-1 and Ro-4 findings. | High | Cn-5 Cn-7 |
| AID-R-002 | Data Integrity Recovery for AI SystemsThe realised impact is data corruption, so a tested way to identify affected CRM records, restore trusted values and validate integrity is part of the poisoning-resistance posture, not just an incident-response nicety. | High | Ro-4 |
| AID-R-007 | External Side-Effect Reconciliation & CompensationBecause the corruption came from the agent repeatedly issuing UpdateCustomerContact calls, recovery cannot stop at restoring a snapshot: the incident-scoped set of agent-issued writes must be reconciled against authoritative record state and each unintended change idempotently reversed, compensated or explicitly dispositioned. This is the recovery counterpart of the Cn-6 gate. | High | Cn-6 |
| AID-D-003.005 | Stateful Session Monitoring: Intent Drift + Invariant-Breach SignalsPrompt mines are delayed and cross-turn, so a session ledger connecting the retrieval of suspicious case text with a later shift into CRM mutation is the detection control whose absence sets C_monitor at 0.65. | Medium | Cn-1 Cn-3 Cn-7 Ro-3 |
WHAT THIS CASE TEACHES
This is the cleanest Cn-6 = 0.00 in the set and shows why AITBM separates Cn-6 from Cn-1: the agent never exceeded its granted CRM permissions, so a permission-only assessment would find nothing wrong, yet the absence of any pre-execution reversibility classification let an ungated bounded-irreversible write execute repeatedly on the authority of anonymous external text.
