{"id":"CVE-2026-73481","summary":"phpList \u003c 3.7.0-RC5 Cross-Site Request Forgery via Bounce Rules","details":"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.","modified":"2026-08-16T03:30:56.790271148Z","published":"2026-08-13T18:48:42.589Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-352"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73481.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73481.json"},{"type":"ADVISORY","url":"https://github.com/phpList/phplist3/releases/tag/v3.7.0-RC5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73481"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/phplist-rc5-cross-site-request-forgery-via-bounce-rules"},{"type":"REPORT","url":"https://github.com/phpList/phplist3/issues/1116"},{"type":"FIX","url":"https://github.com/phpList/phplist3/commit/5159c3ed33a5674a8169472b50d146d97f630746"},{"type":"FIX","url":"https://github.com/phpList/phplist3/pull/1121"},{"type":"PACKAGE","url":"https://github.com/phpList/phplist3"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/phplist/phplist3","events":[{"introduced":"0"},{"fixed":"f69dc97cd3a6705dffb2c7e6c8c5b534bac05e02"},{"fixed":"5159c3ed33a5674a8169472b50d146d97f630746"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.7.0-RC5"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v3.7.0-RC4","v3.7.0-RC3","v3.7.0-RC2","v3.7.0-RC1","v3.6.12-RC2","v3.6.12","v3.6.11-RC1","v3.6.11","v3.6.12-RC","v3.6.9-RC2","v3.6.9-RC1","v3.6.8-RC2","v3.6.8","v3.6.8-RC1","v3.6.7-RC2","v3.6.7-RC1","v3.6.6","v3.6.6-RC3","v3.6.5","v3.6.4-RC2","v3.6.3","v3.6.3-RC2","v3.6.3-RC1","3.6.2","3.6.1","3.6.0","3.5.9","3.5.8","3.5.7","3.5.6","3.5.5","3.5.3","3.5.2","3.5.1","3.5.0","3.4.9","3.4.8","3.4.7","3.4.6","3.4.5","3.4.4","v.3.3.8","3.3.6","v.3.3.5","v3.2.7","v3.2.1","3.2.0","3.2.0-RC1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-73481.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
