Combined with WordPress's permissive REST CORS behavior — which echoes the request `Origin` and sets `Access-Control-Allow-Credentials: true` — 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"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-118194","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-10-30T17:33:39.445031Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-30T18:09:01.200Z"}}]}}
