{"id":"CVE-2026-82564","summary":"Identity tool filter in AshAi accepts operator maps, allowing update or destroy of unidentified records","details":"Authorization Bypass Through User-Controlled Key vulnerability in ash-project ash_ai allows a caller of an identity-configured tool to update or destroy records it never identified, including every row in the table.\n\nIn AshAi.Tool.Execution, identity_filter/3 built the update/destroy filter directly from the raw tool arguments as [{key, Map.get(arguments, to_string(key))}] and passed it to Ash.Query.do_filter/2. A map value is parsed as a predicate expression rather than a literal, so a caller can send {\"public_ref\": {\"not_eq\": \"\u003cown-ref\u003e\"}} and, combined with Ash.Query.limit(1) and Ash.bulk_update!/Ash.bulk_destroy!, retarget the write at a record it never identified; an omitted key yields an IS NULL filter that matches an arbitrary row. The fix casts each identity value to the field type, rejecting non-scalar inputs.\n\nThis issue affects ash_ai: from 0.6.0 before 1.0.0.","aliases":["EEF-CVE-2026-82564","GHSA-jg86-xh36-h5xc"],"modified":"2026-09-03T03:30:17.984749498Z","published":"2026-08-31T01:06:00.526Z","database_specific":{"unresolved_ranges":[{"extracted_events":[{"introduced":"bc2122f78fca6c11d8ec2b9ac53148ec17476460"},{"fixed":"87f616d5bfbf7af43346f0701ae17f853789a602"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"EEF","cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82564.json"},"references":[{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-82564.html"},{"type":"WEB","url":"https://github.com"},{"type":"WEB","url":"https://osv.dev/vulnerability/EEF-CVE-2026-82564"},{"type":"WEB","url":"https://repo.hex.pm"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82564.json"},{"type":"ADVISORY","url":"https://github.com/ash-project/ash_ai/security/advisories/GHSA-jg86-xh36-h5xc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-82564"},{"type":"FIX","url":"https://github.com/ash-project/ash_ai/commit/87f616d5bfbf7af43346f0701ae17f853789a602"},{"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":"87f616d5bfbf7af43346f0701ae17f853789a602"}],"database_specific":{"extracted_events":[{"introduced":"0.6.0"},{"fixed":"1.0.0"}],"source":["DESCRIPTION","REFERENCES"]}}],"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-2026-82564.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:H/VA:N/SC:N/SI:N/SA:N"}]}
