{"id":"CVE-2026-82580","summary":"AshAi echoes raw tool exception messages into the conversation, disclosing internal details","details":"Generation 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":["EEF-CVE-2026-82580","GHSA-5747-6mpw-6m9c"],"modified":"2026-09-01T03:46:31.322119360Z","published":"2026-08-31T01:09:00.192Z","database_specific":{"unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"bc2122f78fca6c11d8ec2b9ac53148ec17476460"},{"fixed":"c68dfbdb220426dc015b58379e95bde8e9f0995a"}]}],"cna_assigner":"EEF","cwe_ids":["CWE-209"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82580.json"},"references":[{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-82580.html"},{"type":"WEB","url":"https://github.com"},{"type":"WEB","url":"https://osv.dev/vulnerability/EEF-CVE-2026-82580"},{"type":"WEB","url":"https://repo.hex.pm"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82580.json"},{"type":"ADVISORY","url":"https://github.com/ash-project/ash_ai/security/advisories/GHSA-5747-6mpw-6m9c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-82580"},{"type":"FIX","url":"https://github.com/ash-project/ash_ai/commit/c68dfbdb220426dc015b58379e95bde8e9f0995a"},{"type":"PACKAGE","url":"https://github.com/ash-project/ash_ai"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ash-project/ash_ai","events":[{"introduced":"c31e6f4b619d9e6f79088fdf4f2a3463941137a6"},{"fixed":"f72b14744996e71df6d73480d617d963f340597b"},{"fixed":"c68dfbdb220426dc015b58379e95bde8e9f0995a"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"0.6.0"},{"fixed":"1.0.0"}]}}],"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://storage.googleapis.com/cve-osv-conversion/osv-output/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"}]}
