{"id":"CVE-2026-4301","state":"PUBLISHED","title":"Rate Star Review Vote <= 1.6.4 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Post Modification via 'rating_id' Parameter","description":"The Rate Star Review Vote - AJAX Reviews, Votes, Star Ratings plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.6.4. The vwrsr_review() AJAX handler lacks both capability checks and nonce verification. The only access control is an is_user_logged_in() check. When the 'form' parameter is set to 'update', the function takes an arbitrary post ID from the user-supplied 'rating_id' GET parameter, sets it as the post ID in the update array, and passes it directly to wp_update_post(). This overwrites the target post's title, content, author (changed to the attacker's user ID), post_type (changed to the plugin's custom post type, default 'review'), and status. Additionally, update_post_meta() is called on the arbitrary post ID at lines 758-763, modifying its metadata. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify the title, content, author, post type, and metadata of arbitrary posts and pages on the site via the 'rating_id' parameter, effectively allowing full post content takeover.","publishedAt":"2026-05-12T07:48:17.336Z","updatedAt":"2026-05-12T12:56:54.390Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["videowhisper Rate Star Review Vote – AJAX Reviews, Votes, Star Ratings"],"affected":[{"vendor":"videowhisper","product":"Rate Star Review Vote – AJAX Reviews, Votes, Star Ratings","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.6.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/107cb15f-4b2e-4ed4-8e8a-4f716f4873db?source=cve","https://plugins.trac.wordpress.org/browser/rate-star-review/trunk/rate-star-review.php#L754","https://plugins.trac.wordpress.org/browser/rate-star-review/tags/1.6.4/rate-star-review.php#L754","https://plugins.trac.wordpress.org/browser/rate-star-review/trunk/rate-star-review.php#L730","https://plugins.trac.wordpress.org/browser/rate-star-review/tags/1.6.4/rate-star-review.php#L730","https://plugins.trac.wordpress.org/browser/rate-star-review/trunk/rate-star-review.php#L758","https://plugins.trac.wordpress.org/browser/rate-star-review/tags/1.6.4/rate-star-review.php#L758"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4301.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4301","state":"PUBLISHED","datePublished":"2026-05-12T07:48:17.336Z","dateUpdated":"2026-05-12T12:56:54.390Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-16T20:01:00.547Z"},"containers":{"cna":{"title":"Rate Star Review Vote <= 1.6.4 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Post Modification via 'rating_id' Parameter","descriptions":[{"lang":"en","value":"The Rate Star Review Vote - AJAX Reviews, Votes, Star Ratings plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.6.4.
