{"id":"EEF-CVE-2026-82580","summary":"AshAi echoes raw tool exception messages into the conversation, disclosing internal details","details":"## Summary\n\nGeneration of Error Message Containing Sensitive Information vulnerability in ash-project ash_ai discloses internal error text to chat users.\n\nIn `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.\n\nThis issue affects ash_ai: from 0.6.0 before 1.0.0.","aliases":["CVE-2026-82580","GHSA-5747-6mpw-6m9c"],"modified":"2026-09-08T02:30:02.976849004Z","published":"2026-08-31T01:09:00.192Z","database_specific":{"cwe_ids":["CWE-209"],"capec_ids":["CAPEC-54"],"cpe_ids":["cpe:2.3:a:ash-project:ash_ai:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://github.com/ash-project/ash_ai/security/advisories/GHSA-5747-6mpw-6m9c"},{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-82580.html"},{"type":"FIX","url":"https://github.com/ash-project/ash_ai/commit/c68dfbdb220426dc015b58379e95bde8e9f0995a"},{"type":"PACKAGE","url":"https://hex.pm/packages/ash_ai"}],"affected":[{"package":{"name":"ash_ai","ecosystem":"Hex","purl":"pkg:hex/ash_ai"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.6.0"},{"fixed":"1.0.0"}]}],"versions":["0.6.0","0.6.1","0.7.0","0.7.1","0.7.2","0.7.3","0.8.0","0.8.1","0.8.2"],"database_specific":{"source":"https://cna.erlef.org/osv/EEF-CVE-2026-82580.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/ash-project/ash_ai","events":[{"introduced":"bc2122f78fca6c11d8ec2b9ac53148ec17476460"},{"fixed":"c68dfbdb220426dc015b58379e95bde8e9f0995a"}]}],"versions":["v0.8.2","v0.8.1","v0.8.0","v0.7.3","v0.7.2","v0.7.1","v0.7.0","v0.6.1","v0.6.0"],"database_specific":{"source":"https://cna.erlef.org/osv/EEF-CVE-2026-82580.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}],"credits":[{"name":"Peter Ullrich","type":"FINDER"},{"name":"Peter Ullrich","type":"REPORTER"},{"name":"Zach Daniel / Ash Project","type":"REMEDIATION_DEVELOPER"},{"name":"Jonatan Männchen / EEF","type":"COORDINATOR"}]}
