{"id":"CVE-2026-82725","summary":"AshPhoenix FilterForm allows filtering across non-public relationships, disclosing private related data","details":"Authorization Bypass Through User-Controlled Key vulnerability in ash-project ash_phoenix lets an attacker who controls filter form parameters filter across relationships the resource author marked non-public, turning the returned rows into a boolean oracle over private related data.\n\nAshPhoenix.FilterForm resolved every relationship hop in the user-supplied path with Ash.Resource.Info.related/2, which traverses private relationships, and only checked the terminal field for publicity. parse_path_and_field/2 also rewrote a field naming a relationship into an extra path segment, so field=some_private_rel was accepted too. Both path and field come straight from form params, and the resulting ref went to Ash.Query.do_filter/2 without the public-only enforcement of Ash.Filter.parse_input/2. The fix resolves each hop with Ash.Resource.Info.public_relationship/2, rejecting the first non-public hop, and requires the terminal field to be public.\n\nThis issue affects ash_phoenix: from 0.6.0-rc.1 before 2.3.25.","aliases":["EEF-CVE-2026-82725","GHSA-7xhg-xphm-f458"],"modified":"2026-09-03T03:30:30.317097146Z","published":"2026-08-31T03:09:25.850Z","database_specific":{"cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82725.json","unresolved_ranges":[{"extracted_events":[{"introduced":"06875682999938f607c970e71b6a80af90e18b3d"},{"fixed":"a3691a3cb0947e8f2dc2c3cbff138a3e6197a15b"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"EEF"},"references":[{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-82725.html"},{"type":"WEB","url":"https://github.com"},{"type":"WEB","url":"https://osv.dev/vulnerability/EEF-CVE-2026-82725"},{"type":"WEB","url":"https://repo.hex.pm"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82725.json"},{"type":"ADVISORY","url":"https://github.com/ash-project/ash_phoenix/security/advisories/GHSA-7xhg-xphm-f458"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-82725"},{"type":"FIX","url":"https://github.com/ash-project/ash_phoenix/commit/a3691a3cb0947e8f2dc2c3cbff138a3e6197a15b"},{"type":"PACKAGE","url":"https://github.com/ash-project/ash_phoenix"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ash-project/ash_phoenix","events":[{"introduced":"81ce20f363ad0904b61fcd893e1bb10c5966a87d"},{"fixed":"1e38e7dc8838426cc94656238d9208759c661c03"},{"fixed":"a3691a3cb0947e8f2dc2c3cbff138a3e6197a15b"}],"database_specific":{"extracted_events":[{"introduced":"0.6.0-rc.1"},{"fixed":"2.3.25"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v2.3.24","v2.3.23","v2.3.22","v2.3.21","v2.3.20","v2.3.19","v2.3.18","v2.3.17","v2.3.10","v2.3.16","v2.3.15","v2.3.14","v2.3.13","v2.3.12","v2.3.11","v2.3.9","v2.3.8","v2.3.7","v2.3.6","v2.3.5","v2.3.4","v2.3.3","v2.3.2","v2.3.1","v2.3.0","v2.2.0","v2.1.26","v2.1.25","v2.1.24","v2.1.23","v2.1.22","v2.1.21","v2.1.20","v2.1.19","v2.1.18","v2.1.17","v2.1.16","v2.1.15","v2.1.14","v2.1.12","v2.1.11","v2.1.10","v2.1.9","v2.1.8","v2.1.7","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.1","v2.0.3","v2.0.2","v2.0.1","v2.0.0-rc.8","v2.0.0-rc.7","v2.0.0-rc.6","v2.0.0-rc.5","v2.0.0-rc.4","v2.0.0-rc.3","v2.0.0-rc.2","v2.0.0-rc.1","v2.0.0-rc.0","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.26","v1.2.25","v1.2.24","v1.2.23","v1.2.22","v1.2.21","v1.2.20","v1.2.19","v1.2.18","v1.2.17","v1.2.16","v1.2.15","v1.2.14","v1.2.13","v1.2.12","v1.2.11","v1.2.10","v1.2.9","v1.2.8","v1.2.7","v1.2.6","v1.2.5","v1.2.4","v1.2.3","v1.2.2","v1.2.1","v1.2.0","v1.1.2","v1.1.1","v1.1.0","v1.1.0-rc.3","v1.1.0-rc.2","v1.1.0-rc.1","v1.1.0-rc.0","v1.0.0-rc.1","v1.0.0-rc.0","v0.7.7","v0.7.6-rc.0","v0.7.5","v0.7.4","v0.7.3","v0.7.2-rc.2","v0.7.2-rc.1","v0.7.2-rc.0","v0.7.1","v0.7.0","v0.6.0-rc.7","v0.6.0-rc.6","v0.6.0-rc.5","v0.6.0-rc.4","v0.6.0-rc.3","v0.6.0-rc.2","v0.6.0-rc.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-82725.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
