{"id":"CVE-2026-85655","state":"PUBLISHED","title":"Enable Media Replace <= 4.2.2 - Missing Authorization to Authenticated (Author+) Post Content Modification via Media Replacement Workflow","description":"The Enable Media Replace plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.2.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with author-level access and above, to modify the post_content of any published post referencing the replaced media — including Administrator-owned posts — making changes immediately visible to unauthenticated visitors. The doReplaceQuery() method performs a database-wide search-and-replace across all posts containing the old media URL without any per-post capability check, meaning a single Author-triggered request can silently overwrite a large number of posts that WordPress's standard admin UI and REST API would otherwise forbid that user from editing.","publishedAt":"2026-10-28T07:48:29.420Z","updatedAt":"2026-10-29T01:41:49.939Z","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":["shortpixel Enable Media Replace"],"affected":[{"vendor":"shortpixel","product":"Enable Media Replace","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.2.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/aff42473-63c6-41ca-8312-058f213e2302?source=cve","https://plugins.trac.wordpress.org/browser/enable-media-replace/tags/4.2.2/build/shortpixel/replacer/src/Replacer.php#L250","https://plugins.trac.wordpress.org/browser/enable-media-replace/tags/4.2.2/classes/ViewController/UploadViewController.php#L59","https://plugins.trac.wordpress.org/browser/enable-media-replace/tags/4.2.2/classes/ViewController/UploadViewController.php#L66","https://plugins.trac.wordpress.org/browser/enable-media-replace/tags/4.2.2/classes/Controller/ReplaceController.php#L253","https://plugins.trac.wordpress.org/browser/enable-media-replace/tags/4.1.9/build/shortpixel/replacer/src/Replacer.php#L250","https://plugins.trac.wordpress.org/browser/enable-media-replace/tags/4.1.9/classes/ViewController/UploadViewController.php#L59","https://plugins.trac.wordpress.org/browser/enable-media-replace/tags/4.1.9/classes/ViewController/UploadViewController.php#L66","https://plugins.trac.wordpress.org/browser/enable-media-replace/tags/4.1.9/classes/Controller/ReplaceController.php#L253","https://github.com/short-pixel-optimizer/enable-media-replace/releases/tag/v4.2.3"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:13:15.269Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/85xxx/CVE-2026-85655.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-85655","state":"PUBLISHED","datePublished":"2026-10-28T07:48:29.420Z","dateUpdated":"2026-10-29T01:41:49.939Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-04T13:13:08.079Z"},"containers":{"cna":{"title":"Enable Media Replace <= 4.2.2 - Missing Authorization to Authenticated (Author+) Post Content Modification via Media Replacement Workflow","descriptions":[{"lang":"en","value":"The Enable Media Replace plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.2.2.
