{"id":"CVE-2026-34375","summary":"AVideo Vulnerable to Reflected XSS via Unsanitized plugin Parameter in YPTWallet Stripe Payment Page","details":"WWBN AVideo is an open source video platform. In versions up to and including 26.0, the YPTWallet Stripe payment confirmation page directly echoes the `$_REQUEST['plugin']` parameter into a JavaScript block without any encoding or sanitization. The `plugin` parameter is not included in any of the framework's input filter lists defined in `security.php`, so it passes through completely raw. An attacker can inject arbitrary JavaScript by crafting a malicious URL and sending it to a victim user. The same script block also outputs the current user's username and password hash via `User::getUserName()` and `User::getUserPass()`, meaning a successful XSS exploitation can immediately exfiltrate these credentials. Commit fa0bc102493a15d79fe03f86c07ab7ca1b5b63e2 fixes the issue.","aliases":["GHSA-pm37-62g7-p768"],"modified":"2026-08-12T03:51:20.156310308Z","published":"2026-03-27T18:17:32.604Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34375.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34375.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-pm37-62g7-p768"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34375"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/fa0bc102493a15d79fe03f86c07ab7ca1b5b63e2"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"fixed":"fa0bc102493a15d79fe03f86c07ab7ca1b5b63e2"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"26.0"}]}}],"versions":["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-2026-34375.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N"}]}
