{"id":"CVE-2026-34375","aliases":["GHSA-pm37-62g7-p768"],"url":"https://o3.security/vulnerability/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.","published":"2026-03-27T18:17:32.604Z","modified":"2026-08-12T03:51:20.156310308Z","cvss":{"score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N"},"epss":{"score":0.00296,"percentile":0.223,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"wwbn/avideo","fixedVersion":null}],"fix":{"url":"https://github.com/WWBN/AVideo/commit/fa0bc102493a15d79fe03f86c07ab7ca1b5b63e2","label":"WWBN/AVideo@fa0bc10"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:20.156310308Z"}}
