Attackers can request a reset for a victim so AuthDb::notifyUser() emails a link pointing to their host, capturing the reset key when opened to take over accounts including administrators.","published":"2026-11-13T16:23:34.805Z","modified":"2026-11-15T02:46:40.443855728Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/meeting-room-booking-system/mrbs-code/commit/92f6f5610072ddb9e1b38074c410fc8be56947ed","label":"meeting-room-booking-system/mrbs-code@92f6f56"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/129xxx/CVE-2026-129134.json"},{"type":"ADVISORY","url":"https://github.com/meeting-room-booking-system/mrbs-code/releases/tag/v1.13.0"},{"type":"ADVISORY","url":"https://github.com/meeting-room-booking-system/mrbs-code/security/advisories/GHSA-73cv-hx7f-9v27"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-129134"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/mrbs-before-1.13.0-password-reset-poisoning-via-host-header-injection"},{"type":"FIX","url":"https://github.com/meeting-room-booking-system/mrbs-code/commit/92f6f5610072ddb9e1b38074c410fc8be56947ed"},{"type":"ARTICLE","url":"https://github.com/meeting-room-booking-system/mrbs-code/blob/299686ed64174a66448699f5ca0fb5e0e0ea9faa/web/lib/MRBS/Auth/AuthDb.php#L613"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-11-15T02:46:40.443855728Z"}}
