{"id":"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=\u003cemail\u003e&pass=\u003cHASH\u003e where \u003cHASH\u003e 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.","aliases":["GHSA-5w8w-26ch-v5cw"],"modified":"2026-07-15T01:49:08.989826180Z","published":"2026-05-11T20:32:05.504Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43875.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-598"]},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"fixed":"977cd6930a97571a26da4239e25c8096dd4ecbc1"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"29.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"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-2026-43875.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N"}]}
