CVE-2026-73481
phpList < 3.7.0-RC5 Cross-Site Request Forgery via Bounce Rules
Published Aug 13, 2026
CVSS 4.0 · 5.3 Medium
EPSS < 1%
KEV · Not listed
Description
phpList before 3.7.0-RC5 fail to enforce CSRF token validation on the bounce rule deletion endpoint (bouncerules.php / bouncerule.php). The deletion is performed via a GET request (?page=bouncerules&del=N), and the central CSRF check (verifyCsrfGetToken) is invoked with enforce=false, so it only validates the token when a 'tk' parameter is present. A remote attacker can trick an authenticated administrator into loading a crafted URL (e.g., embedded in an image tag) to delete arbitrary bounce rules from the phplist_bounceregex table without a valid CSRF token.
