{"id":"CVE-2026-43875","aliases":["GHSA-5w8w-26ch-v5cw"],"url":"https://o3.security/vulnerability/CVE-2026-43875","summary":"WWBN AVideo: Password Hash Leaked in MobileManager OAuth Redirect URL Enables Account Takeover","details":"WWBN AVideo is an open source video platform. In versions up to and including 29.0, plugin/MobileManager/oauth2.php completes an OAuth login by sending an HTTP 302 Location: oauth2Success.php?user=<email>&pass=<HASH> where <HASH> is the victim's stored password hash (md5(hash(\"whirlpool\", sha1(password)))) read directly from the users table. AVideo's own login endpoint (objects/login.json.php) accepts an encodedPass=1 flag that bypasses hashing and performs a direct string comparison between the supplied value and the stored hash. Anyone who captures the redirect URL — via server logs, referrer leakage, or browser history — therefore obtains a credential equivalent to the plaintext password and can fully take over the account, including admin accounts. Commit 977cd6930a97571a26da4239e25c8096dd4ecbc1 contains an updated fix.","published":"2026-05-11T20:32:05.504Z","modified":"2026-08-12T03:51:28.212088311Z","cvss":{"score":6.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N"},"epss":{"score":0.00285,"percentile":0.20408,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"wwbn/avideo","fixedVersion":null}],"fix":{"url":"https://github.com/WWBN/AVideo/commit/977cd6930a97571a26da4239e25c8096dd4ecbc1","label":"WWBN/AVideo@977cd69"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43875.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-5w8w-26ch-v5cw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43875"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/977cd6930a97571a26da4239e25c8096dd4ecbc1"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:28.212088311Z"}}
