Lifecycle Timeline
3DescriptionCVE.org
Generation of Error Message Containing Sensitive Information vulnerability in ash-project ash_ai discloses internal error text to chat users.
In AshAi.ToolLoop and AshAi.Tools, an exception raised while executing a tool was serialized verbatim with Exception.message/1 into the tool-result content. That content is appended to the conversation, emitted as a {:tool_result, ...} stream event, and sent back to the model, which typically relays it to the user. No filtering happened first, so anything raised inside a tool callback or lifecycle hook (database constraint messages, adapter errors, query fragments, policy or validation internals) was echoed as-is. A chat user who can steer tool arguments into a raising code path receives the raw internal text. The fix routes raised tool errors through the same safe formatter used for other tool errors.
This issue affects ash_ai: from 0.6.0 before 1.0.0.
AnalysisAI
Unfiltered exception serialization in ash_ai 0.6.0-0.x leaks internal application details - database schema, raw SQL fragments, policy module names - to authenticated chat users via the LLM conversation stream. AshAi.ToolLoop and AshAi.Tools used Elixir's Exception.message/1 verbatim to encode any raised tool exception into the tool-result payload, which the language model then relayed to the requesting user. …

Vulnerability AssessmentAI
| Exploitation | The attacker must hold an authenticated session with access to the AI chat interface (CVSS PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N) accurately characterizes a moderate, network-accessible information-disclosure risk: no special attack conditions are required beyond holding authenticated access to the chat interface. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade ash_ai to version 1.0.0 or later, which applies commit c68dfbdb220426dc015b58379e95bde8e9f0995a. … Detailed patch versions, workarounds, and compensating controls in full report. |
