{"id":"CVE-2026-0693","state":"PUBLISHED","title":"Allow HTML in Category Descriptions <= 1.2.4 - Authenticated (Administrator+) Stored Cross-Site Scripting via Category Descriptions","description":"The Allow HTML in Category Descriptions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via category descriptions in all versions up to, and including, 1.2.4. This is due to the plugin unconditionally removing the `wp_kses_data` output filter for term_description, link_description, link_notes, and user_description fields without checking user capabilities. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in category descriptions that will execute whenever a user accesses a page where the category description is displayed. This only affects multi-site installations and installations where unfiltered_html has been disabled.","publishedAt":"2026-02-14T06:42:32.915Z","updatedAt":"2026-04-08T17:17:23.778Z","severity":{"score":4.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["arnoesterhuizen Allow HTML in Category Descriptions"],"affected":[{"vendor":"arnoesterhuizen","product":"Allow HTML in Category Descriptions","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.2.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/b63c9a5a-fa3e-46c7-9d9c-7c209fc5713a?source=cve","https://plugins.trac.wordpress.org/browser/allow-html-in-category-descriptions/trunk/html-in-category-descriptions.php#L23","https://plugins.trac.wordpress.org/browser/allow-html-in-category-descriptions/tags/1.2.4/html-in-category-descriptions.php#L23"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/0xxx/CVE-2026-0693.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-0693","state":"PUBLISHED","datePublished":"2026-02-14T06:42:32.915Z","dateUpdated":"2026-04-08T17:17:23.778Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-07T20:58:33.120Z"},"containers":{"cna":{"title":"Allow HTML in Category Descriptions <= 1.2.4 - Authenticated (Administrator+) Stored Cross-Site Scripting via Category Descriptions","descriptions":[{"lang":"en","value":"The Allow HTML in Category Descriptions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via category descriptions in all versions up to, and including, 1.2.4.
