{"id":"CVE-2026-4005","state":"PUBLISHED","title":"Coachific Shortcode <= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'userhash' Shortcode Attribute","description":"The Coachific Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'userhash' shortcode attribute in all versions up to and including 1.0. This is due to insufficient input sanitization and output escaping. The plugin uses sanitize_text_field() on the 'userhash' parameter, which strips HTML tags but does not escape characters significant in a JavaScript string context (such as double quotes, semicolons, and parentheses). The sanitized value is then directly interpolated into a JavaScript string within a <script> tag on line 29 without any JavaScript-specific escaping (e.g., wp_json_encode() or esc_js()). 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":"2026-04-15T08:28:14.507Z","updatedAt":"2026-04-16T13:39:08.598Z","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":["coachific Coachific Shortcode"],"affected":[{"vendor":"coachific","product":"Coachific Shortcode","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/3d91158c-0b34-460e-9fdb-b99165ebca78?source=cve","https://plugins.trac.wordpress.org/browser/coachific-shortcode/trunk/coachific.php#L29","https://plugins.trac.wordpress.org/browser/coachific-shortcode/tags/1.0/coachific.php#L29","https://plugins.trac.wordpress.org/browser/coachific-shortcode/trunk/coachific.php#L13","https://plugins.trac.wordpress.org/browser/coachific-shortcode/tags/1.0/coachific.php#L13"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4005.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4005","state":"PUBLISHED","datePublished":"2026-04-15T08:28:14.507Z","dateUpdated":"2026-04-16T13:39:08.598Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-11T18:56:10.776Z"},"containers":{"cna":{"title":"Coachific Shortcode <= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'userhash' Shortcode Attribute","descriptions":[{"lang":"en","value":"The Coachific Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'userhash' shortcode attribute in all versions up to and including 1.0.
