Combined with WordPress's permissive REST CORS behavior \u2014 which echoes the request `Origin` and sets `Access-Control-Allow-Credentials: true` \u2014 this allows an unauthenticated attacker to read REST API GET responses as a logged-in victim, exposing role-restricted and private post/page content, victim user profile data via `/wp-json/wp/v2/users/me`, and comments the victim is authorized to see. This requires the attacker to lure a logged-in user into visiting an attacker-controlled page that issues credentialed cross-origin `fetch` requests against the target site's REST API; no nonce or further victim interaction beyond the page visit is needed."}], "title": "Page and Post Restriction <= 1.6.1 - Unauthenticated Authentication Bypass via REST API Nonce Bypass via Cookie Re-Authentication", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/2785a4e1-64f3-4b20-b0b3-7030bd88438c?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/page-and-post-restriction/tags/1.6.0/page-and-post-restriction.php#L79"}, {"url": "https://plugins.trac.wordpress.org/browser/page-and-post-restriction/tags/1.6.0/page-and-post-restriction.php#L54"}, {"url": "https://plugins.trac.wordpress.org/browser/page-and-post-restriction/tags/1.6.0/page-and-post-restriction.php#L78"}, {"url": "https://plugins.trac.wordpress.org/browser/page-and-post-restriction?rev=3771992"}, {"url": "https://plugins.trac.wordpress.org/changeset/3771992/page-and-post-restriction/trunk/page-and-post-restriction.php"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-287 Improper Authentication", "cweId": "CWE-287", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N", "baseScore": 6.5, "baseSeverity": "MEDIUM"}}], "credits": [{"lang": "en", "type": "finder", "value": "Wordfence PRISM"}], "timeline": [{"time": "2026-10-27T19:14:32.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-10-29T17:04:23.000Z", "lang": "en", "value": "Disclosed"}]}}}
