{"id":"CVE-2026-86729","summary":"WWBN AVideo Unrestricted Authentication Attempts via get_api_preauthorize","details":"WWBN AVideo through commit e01e41ecc (no patched version available) exposes get_api_preauthorize in plugin/API/API.php as a second, undocumented login path. Unlike get_api_signIn, which enforces a rate limit of 10 attempts per 5 minutes via checkRateLimit(), get_api_preauthorize performs the same credential check with no throttling for any client, allowing unlimited remote password guessing against arbitrary accounts, including admin. The endpoint also acts as a credential oracle: it returns the message \"Invalid credentials\" for both correct and incorrect passwords, while the users_id field in the response body discloses the authenticated identity (users_id:1 on success, users_id:0 on failure), and a correct password establishes a session cookie that remains usable for authenticated API requests. Together these issues permit unauthenticated brute-force account takeover.","aliases":["GHSA-vvqm-mgc5-hhx3"],"modified":"2026-09-12T03:30:38.031484829Z","published":"2026-09-08T15:14:00.187Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86729.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-307"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86729.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-vvqm-mgc5-hhx3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-86729"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/wwbn-avideo-unrestricted-authentication-attempts-via-get-api-preauthorize"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"last_affected":"2386f39caea1d2ef36267b252fa76af283294623"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"29.0"}],"source":"AFFECTED_FIELD"}}],"versions":["29.0","26.0","25.0","24.0","22.0","21.0","18.0","14.3.1","14.3","12.4","11.6","11.5","11.1.1","11.1","11","10.8","8.9.1","8.9","8.7","8.6","8.5","8.1","7.8","7.7","7.6","7.4","7.3","7.2","4.0","3.4","2.7","2.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-86729.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
