{"id":"CVE-2026-2512","state":"PUBLISHED","title":"Code Embed <= 2.5.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via Custom Fields","description":"The Code Embed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via custom field meta values in all versions up to, and including, 2.5.1. This is due to the plugin's sanitization function `sec_check_post_fields()` only running on the `save_post` hook, while WordPress allows custom fields to be added via the `wp_ajax_add_meta` AJAX endpoint without triggering `save_post`. The `ce_filter()` function then outputs these unsanitized meta values directly into page content without escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","publishedAt":"2026-03-18T15:28:28.763Z","updatedAt":"2026-04-08T16:46:21.048Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["dartiss Code Embed"],"affected":[{"vendor":"dartiss","product":"Code Embed","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.5.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/375ed04b-a3cb-4e60-83c8-18bff583aaf4?source=cve","https://plugins.trac.wordpress.org/browser/simple-embed-code/trunk/includes/add-embeds.php#L84","https://plugins.trac.wordpress.org/browser/simple-embed-code/trunk/includes/add-embeds.php#L20","https://plugins.trac.wordpress.org/browser/simple-embed-code/trunk/includes/secure.php#L25","https://plugins.trac.wordpress.org/changeset/3482994/"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/2xxx/CVE-2026-2512.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-2512","state":"PUBLISHED","datePublished":"2026-03-18T15:28:28.763Z","dateUpdated":"2026-04-08T16:46:21.048Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-14T01:55:08.510Z"},"containers":{"cna":{"title":"Code Embed <= 2.5.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via Custom Fields","descriptions":[{"lang":"en","value":"The Code Embed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via custom field meta values in all versions up to, and including, 2.5.1.
