This is due to the Register & Login add-on's before_email_success_msg() function, in its register_login_action='update' flow, trusting an attacker-supplied user_id value and passing it to wp_update_user() without any ownership or capability check. Because the super_save_form AJAX action also enforces no capability check, any authenticated user with Subscriber-level access and above can create the required malicious form (register_login_action='update' with register_login_user_id_update='true') and then submit it with user_id set to an administrator's ID along with a new user_pass/user_email. This makes it possible for authenticated attackers with Subscriber-level access and above to overwrite the credentials of arbitrary existing accounts — including administrators — resulting in account takeover and full site compromise.","state":0,"publishedAt":"2026-10-02T05:30:17.19+00:00","modifiedAt":"2026-10-03T15:42:50.803+00:00","affected":[{"ecosystem":"Vendor product","name":"Super Forms – Drag & Drop Form Builder","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"WebRehab\",\n                    \"product\": \"Super Forms – Drag & Drop Form Builder\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"6.3.316\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/94297481-9ebb-42cb-9362-be8bc52b126f?source=cve","https://github.com/RensTillmann/super-forms/pull/205"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-15897","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-15897","identifiers":["CVE-2026-15897"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
