{"id":"CVE-2026-13733","state":"PUBLISHED","title":"Download Manager <= 3.3.60 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'no_data_msg' Shortcode Attribute","description":"The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'no_data_msg' Shortcode Attribute in all versions up to, and including, 3.3.60 due to insufficient input sanitization and output 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. Although wp_kses_post is applied to post content on save, it only strips HTML tokens and does not neutralize C-style escape sequences embedded within shortcode attribute values, meaning contributors can craft a payload that survives the kses filter and is silently reconstructed into a raw script tag at render time.","publishedAt":"2026-07-01T07:53:38.269Z","updatedAt":"2026-07-01T10:32:03.787Z","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":["codename065 Download Manager"],"affected":[{"vendor":"codename065","product":"Download Manager","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.3.60","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/ebf96aa9-2ee7-4411-8f43-3e8d023197bd?source=cve","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.59/src/Package/views/all-packages-shortcode.php#L396","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.60/src/Package/views/all-packages-shortcode.php#L396","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.60/src/Package/Shortcodes.php#L398","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.60/src/Package/Shortcodes.php#L37","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.59/src/Package/Shortcodes.php#L398","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.59/src/Package/Shortcodes.php#L37","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3590868%40download-manager&new=3590868%40download-manager&sfp_email=&sfph_mail="],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/13xxx/CVE-2026-13733.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-13733","state":"PUBLISHED","datePublished":"2026-07-01T07:53:38.269Z","dateUpdated":"2026-07-01T10:32:03.787Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-29T14:43:51.291Z"},"containers":{"cna":{"title":"Download Manager <= 3.3.60 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'no_data_msg' Shortcode Attribute","descriptions":[{"lang":"en","value":"The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'no_data_msg' Shortcode Attribute in all versions up to, and including, 3.3.60 due to insufficient input sanitization and output escaping.
