{"id":"CVE-2026-5357","state":"PUBLISHED","title":"Download Manager <= 3.3.52 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","description":"The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sid' parameter of the 'wpdm_members' shortcode in versions up to and including 3.3.52. This is due to insufficient input sanitization and output escaping on the user-supplied 'sid' shortcode attribute. The sid parameter is extracted without sanitization in the members() function and stored via update_post_meta(), then echoed directly into an HTML id attribute in the members.php template without applying esc_attr(). 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 the injected page.","publishedAt":"2026-04-09T02:25:05.524Z","updatedAt":"2026-04-09T16:16:07.276Z","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":"3.3.52","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/27fc81b0-c03a-4de7-bc38-791401d1685b?source=cve","https://plugins.trac.wordpress.org/browser/download-manager/trunk/src/User/views/members.php#L10","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.51/src/User/views/members.php#L10","https://plugins.trac.wordpress.org/browser/download-manager/trunk/src/User/User.php#L175","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.51/src/User/User.php#L175","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3501300%40download-manager&new=3501300%40download-manager&sfp_email=&sfph_mail="],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/5xxx/CVE-2026-5357.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-5357","state":"PUBLISHED","datePublished":"2026-04-09T02:25:05.524Z","dateUpdated":"2026-04-09T16:16:07.276Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-01T17:01:10.398Z"},"containers":{"cna":{"title":"Download Manager <= 3.3.52 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","descriptions":[{"lang":"en","value":"The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sid' parameter of the 'wpdm_members' shortcode in versions up to and including 3.3.52.
