{"id":"CVE-2026-86719","state":"PUBLISHED","title":"WWBN AVideo CustomizeUser Cross-Site Request Forgery Session Hijacking","description":"WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 (master) contains a cross-site request forgery vulnerability in the CustomizeUser plugin endpoint plugin/CustomizeUser/swapUser.json.php. The endpoint takes users_id from $_REQUEST and invokes User::swapUser() without calling forbidIfNotPost() or forbidIfInvalidToken(), and the global autoCSRFGuard() check only runs for POST requests to *.json.php, so the action is reachable via GET. An attacker who causes an authenticated administrator's browser to issue a cross-origin GET (for example via an <img> tag or link) can replace that administrator's session with a non-admin user account, causing the administrator to lose administrative access until the swap is cancelled; swapping to another administrator account is rejected, so this is not privilege escalation. The JSON response also discloses the session_id. The CustomizeUser plugin is enabled by default, and no patch was available at the time of publication.","publishedAt":"2026-09-08T15:13:53.401Z","updatedAt":"2026-09-10T15:02:51.918Z","severity":{"score":5.3,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["WWBN AVideo"],"affected":[{"vendor":"WWBN","product":"AVideo","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"c3edcc274c389816d434acadac07ee78eaf330c1","versionType":"git"}]}],"references":["https://github.com/WWBN/AVideo/security/advisories/GHSA-xrp7-6w7g-q7fx","https://www.vulncheck.com/advisories/wwbn-avideo-customizeuser-cross-site-request-forgery-session-hijacking"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/86xxx/CVE-2026-86719.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-86719","state":"PUBLISHED","datePublished":"2026-09-08T15:13:53.401Z","dateUpdated":"2026-09-10T15:02:51.918Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-09-08T11:30:41.420Z"},"containers":{"cna":{"title":"WWBN AVideo CustomizeUser Cross-Site Request Forgery Session Hijacking","descriptions":[{"lang":"en","value":"WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 (master) contains a cross-site request forgery vulnerability in the CustomizeUser plugin endpoint plugin/CustomizeUser/swapUser.json.php.
