{"id":"CVE-2026-56679","summary":"9Router: Mass assignment in PATCH /api/settings allows authenticated authorization downgrade","details":"9Router is an AI router & token saver. Prior to 0.5.4, the PATCH /api/settings endpoint writes the entire request body to persistent settings without a field whitelist, allowing an authenticated user to set security-critical fields such as requireLogin and disable authentication for the whole application, exposing protected routes such as /api/keys and /api/providers to unauthenticated access. This issue is reported as fixed in version 0.5.4.","aliases":["GHSA-vmjq-hvgq-2wv4"],"modified":"2026-07-18T03:41:43.660747256Z","published":"2026-07-15T20:50:30.458Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-915"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56679.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56679.json"},{"type":"ADVISORY","url":"https://github.com/decolua/9router/security/advisories/GHSA-vmjq-hvgq-2wv4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-56679"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/decolua/9router","events":[{"introduced":"0"},{"fixed":"7354c5e5f4d0e53d8de9d6edf1773dce74144fec"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.5.4"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.5.2","v0.4.80","v0.4.71","v0.4.66","v0.4.63","v0.4.62","v0.4.59","v0.4.58","v0.4.55","v0.4.52","v0.4.50","v0.4.49","v0.4.46","v0.4.44","v0.4.41","v0.4.39","v0.4.38","v0.4.37","v0.4.36","v0.4.33","v0.4.31","v0.4.30","v0.4.29","v0.4.28","v0.4.27","v0.4.25","v0.4.20","v0.4.19","v0.4.18","v0.4.16","v0.4.14","v0.4.13","v0.4.12","v0.4.11","v0.4.10","v0.4.8","v0.4.6","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.3.98","v0.3.97","v0.3.91","v0.3.90","v0.3.89","v0.3.87","v0.3.86","v0.3.83","v0.3.75","v0.3.47","v0.3.42","v0.3.34","v0.3.17","v0.2.89","v0.2.79","v0.2.71","v0.2.70","v0.2.67","v0.2.56","v0.2.52","v0.2.43","v0.2.36","v0.2.31","v0.2.27","v0.2.21"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-56679.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
