{"id":"CVE-2026-6641","state":"PUBLISHED","title":"Media Library Assistant <= 3.35 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'mla_link_href' Shortcode Parameter","description":"The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'mla_gallery' shortcode in versions up to and including 3.35. This is due to insufficient input sanitization and output escaping on the mla_link_href parameter when mla_output is set to 'paginate_links', where the _paginate_links() function processes the value through mla_process_shortcode_parameter() and _replace_query_parameter() without proper URL escaping, then outputs it directly in href attributes without applying esc_url(). 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":"2026-09-11T07:39:06.595Z","updatedAt":"2026-09-11T13:58:17.628Z","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":["dglingren Media Library Assistant"],"affected":[{"vendor":"dglingren","product":"Media Library Assistant","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.35","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/13602c35-a0f7-4651-af9a-0be9e581893a?source=cve","https://plugins.trac.wordpress.org/browser/media-library-assistant/tags/3.34/includes/class-mla-shortcodes.php#L39","https://plugins.trac.wordpress.org/browser/media-library-assistant/trunk/includes/class-mla-shortcode-support.php#L2484","https://plugins.trac.wordpress.org/browser/media-library-assistant/tags/3.34/includes/class-mla-shortcode-support.php#L2484","https://plugins.trac.wordpress.org/browser/media-library-assistant/trunk/includes/class-mla-shortcode-support.php#L2449","https://plugins.trac.wordpress.org/browser/media-library-assistant/tags/3.34/includes/class-mla-shortcode-support.php#L2449","https://plugins.trac.wordpress.org/browser/media-library-assistant/trunk/includes/class-mla-shortcodes.php#L39","https://plugins.trac.wordpress.org/changeset/3512155/"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6641.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6641","state":"PUBLISHED","datePublished":"2026-09-11T07:39:06.595Z","dateUpdated":"2026-09-11T13:58:17.628Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-19T22:06:28.199Z"},"containers":{"cna":{"title":"Media Library Assistant <= 3.35 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'mla_link_href' Shortcode Parameter","descriptions":[{"lang":"en","value":"The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'mla_gallery' shortcode in versions up to and including 3.35.
