{"id":"CVE-2026-12408","state":"PUBLISHED","title":"Slim SEO <= 4.9.8 - Authenticated (Contributor+) Insufficient Authorization to Private Content Disclosure via 'object.ID' Parameter","description":"The Slim SEO – A Fast & Automated SEO Plugin For WordPress plugin for WordPress is vulnerable to Unauthorized Private Content Disclosure in all versions up to, and including, 4.9.8 via the `/wp-json/slim-seo/meta-tags/ai` REST API endpoint. This is due to the endpoint's `permission_callback` performing only a top-level `edit_posts` capability check without verifying that the requesting user has read access to the specific post supplied via the `object.ID` parameter, allowing the `generate` function to pass the attacker-controlled post ID to `Data::get_post_content()`, which calls `get_post()` regardless of post status or ownership. This makes it possible for authenticated attackers with Contributor-level access and above to retrieve AI-generated summaries of the raw `post_content` of arbitrary posts they are not authorized to view — including private posts, drafts, pending, future, and password-protected content authored by other users — with the substance of the protected content disclosed via the HTTP response.","publishedAt":"2026-07-01T07:53:37.500Z","updatedAt":"2026-07-01T10:32:04.144Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["rilwis Slim SEO – A Fast & Automated SEO Plugin For WordPress"],"affected":[{"vendor":"rilwis","product":"Slim SEO – A Fast & Automated SEO Plugin For WordPress","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.9.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/6e6603a0-8f35-49fb-a517-ba6344538c4d?source=cve","https://plugins.trac.wordpress.org/browser/slim-seo/tags/4.9.8/src/MetaTags/AI.php#L55","https://plugins.trac.wordpress.org/browser/slim-seo/tags/4.9.8/src/MetaTags/AI.php#L21","https://plugins.trac.wordpress.org/browser/slim-seo/tags/4.9.8/src/MetaTags/Data.php#L117","https://plugins.trac.wordpress.org/browser/slim-seo/tags/4.9.5/src/MetaTags/AI.php#L55","https://plugins.trac.wordpress.org/browser/slim-seo/tags/4.9.5/src/MetaTags/AI.php#L21","https://plugins.trac.wordpress.org/browser/slim-seo/tags/4.9.5/src/MetaTags/Data.php#L117","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3576523%40slim-seo&new=3576523%40slim-seo&sfp_email=&sfph_mail="],"weaknesses":["CWE-200"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/12xxx/CVE-2026-12408.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-12408","state":"PUBLISHED","datePublished":"2026-07-01T07:53:37.500Z","dateUpdated":"2026-07-01T10:32:04.144Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-16T14:37:03.010Z"},"containers":{"cna":{"title":"Slim SEO <= 4.9.8 - Authenticated (Contributor+) Insufficient Authorization to Private Content Disclosure via 'object.ID' Parameter","descriptions":[{"lang":"en","value":"The Slim SEO – A Fast & Automated SEO Plugin For WordPress plugin for WordPress is vulnerable to Unauthorized Private Content Disclosure in all versions up to, and including, 4.9.8 via the `/wp-json/slim-seo/meta-tags/ai` REST API endpoint.
