This is due to the `check_permissions()` method only checking for `edit_posts` capability instead of an administrator-level capability. This makes it possible for authenticated attackers, with Contributor-level access and above, to list, create, modify, toggle, duplicate, and delete site-wide content restriction rules, potentially exposing restricted content or denying legitimate user access."}],"title":"User Registration & Membership <= 5.1.4 - Missing Authorization to Authenticated (Contributor+) Content Access Rule Manipulation","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/7bb5a5a2-9644-4850-a5f9-7c925af000c8?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/user-registration/tags/5.1.1/modules/content-restriction/includes/RestApi/controllers/version1/class-urcr-content-access-rules.php#L116"},{"url":"https://plugins.trac.wordpress.org/browser/user-registration/trunk/modules/content-restriction/includes/RestApi/controllers/version1/class-urcr-content-access-rules.php#L116"},{"url":"https://plugins.trac.wordpress.org/changeset/3485702/user-registration/trunk/modules/content-restriction/includes/RestApi/controllers/version1/class-urcr-content-access-rules.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","baseScore":5.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"darkestmode"}],"timeline":[{"time":"2026-03-12T16:42:35.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-03-23T11:24:15.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-25T19:20:55.886633Z","id":"CVE-2026-4056","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-25T19:21:07.947Z"}}]}}
