{"id":"CVE-2026-118194","state":"PUBLISHED","title":"Page and Post Restriction <= 1.6.1 - Unauthenticated Authentication Bypass via REST API Nonce Bypass via Cookie Re-Authentication","description":"The Page and Post Restriction plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.6.1 This is due to the `papr_restrict_page_post_rest_api()` function, hooked on `rest_pre_dispatch`, re-authenticating the current user from the `wordpress_logged_in` cookie via `wp_set_current_user()` for any GET or HEAD REST request where the current user is 0, without verifying a REST nonce — silently undoing the nonce-zeroing that WordPress core's `rest_cookie_check_errors()` performs on cookie-authenticated requests that lack an `X-WP-Nonce` header or `_wpnonce` parameter. 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.","publishedAt":"2026-10-30T05:35:50.445Z","updatedAt":"2026-10-30T18:09:01.200Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["cyberlord92 Page and Post Restriction"],"affected":[{"vendor":"cyberlord92","product":"Page and Post Restriction","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.6.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/2785a4e1-64f3-4b20-b0b3-7030bd88438c?source=cve","https://plugins.trac.wordpress.org/browser/page-and-post-restriction/tags/1.6.0/page-and-post-restriction.php#L79","https://plugins.trac.wordpress.org/browser/page-and-post-restriction/tags/1.6.0/page-and-post-restriction.php#L54","https://plugins.trac.wordpress.org/browser/page-and-post-restriction/tags/1.6.0/page-and-post-restriction.php#L78","https://plugins.trac.wordpress.org/browser/page-and-post-restriction?rev=3771992","https://plugins.trac.wordpress.org/changeset/3771992/page-and-post-restriction/trunk/page-and-post-restriction.php"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-30T18:20:07.061Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/118xxx/CVE-2026-118194.json","commit":"55f8edbf9d47efa62275e8ca91bb2e15e821b559","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-118194","state":"PUBLISHED","datePublished":"2026-10-30T05:35:50.445Z","dateUpdated":"2026-10-30T18:09:01.200Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-10-27T18:59:48.641Z"},"containers":{"cna":{"title":"Page and Post Restriction <= 1.6.1 - Unauthenticated Authentication Bypass via REST API Nonce Bypass via Cookie Re-Authentication","descriptions":[{"lang":"en","value":"The Page and Post Restriction plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.6.1 This is due to the `papr_restrict_page_post_rest_api()` function, hooked on `rest_pre_dispatch`, re-authenticating the current user from the `wordpress_logged_in` cookie via `wp_set_current_user()` for any GET or HEAD REST request where the current user is 0, without verifying a REST nonce — silently undoing the nonce-zeroing that WordPress core's `rest_cookie_check_errors()` performs on cookie-authenticated requests that lack an `X-WP-Nonce` header or `_wpnonce` parameter.
