{"id":"EEF-CVE-2026-82564","summary":"Identity tool filter in AshAi accepts operator maps, allowing update or destroy of unidentified records","details":"## Summary\n\nAuthorization 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":["CVE-2026-82564","GHSA-jg86-xh36-h5xc"],"modified":"2026-09-08T18:30:39.812611780Z","published":"2026-08-31T01:06:00.526Z","database_specific":{"capec_ids":["CAPEC-77"],"cpe_ids":["cpe:2.3:a:ash-project:ash_ai:*:*:*:*:*:*:*:*"],"cwe_ids":["CWE-639"]},"references":[{"type":"ADVISORY","url":"https://github.com/ash-project/ash_ai/security/advisories/GHSA-jg86-xh36-h5xc"},{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-82564.html"},{"type":"FIX","url":"https://github.com/ash-project/ash_ai/commit/87f616d5bfbf7af43346f0701ae17f853789a602"},{"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-2026-82564.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/ash-project/ash_ai","events":[{"introduced":"bc2122f78fca6c11d8ec2b9ac53148ec17476460"},{"fixed":"87f616d5bfbf7af43346f0701ae17f853789a602"}]}],"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-2026-82564.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"}],"credits":[{"name":"Peter Ullrich","type":"FINDER"},{"name":"Peter Ullrich","type":"REPORTER"},{"name":"Jonatan Männchen / EEF","type":"REMEDIATION_DEVELOPER"},{"name":"Zach Daniel / Ash Project","type":"REMEDIATION_REVIEWER"},{"name":"Jonatan Männchen / EEF","type":"COORDINATOR"}]}
