CVE-2026-82580

AshAi echoes raw tool exception messages into the conversation, disclosing internal details

Published Aug 31, 2026 CVSS 4.0 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
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.
