{"id":"CVE-2026-15665","state":"PUBLISHED","title":"Fluent Support <= 2.3.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'redirect-to' Shortcode Attribute","description":"The Fluent Support – Helpdesk & Customer Support Ticket System plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'redirect-to' Shortcode Attribute in all versions up to, and including, 2.3.0 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. The XSS payload is in a hidden attribute so it only fires in specific browsers when specific access keys are used making exploitation unlikely.","publishedAt":"2026-07-24T06:51:58.346Z","updatedAt":"2026-07-24T20:26:51.110Z","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":["wpmanageninja Fluent Support – Helpdesk & Customer Support Ticket System"],"affected":[{"vendor":"wpmanageninja","product":"Fluent Support – Helpdesk & Customer Support Ticket System","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.3.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/0c963224-e680-4ca6-85ae-07cd0ee6c1d4?source=cve","https://plugins.trac.wordpress.org/browser/fluent-support/tags/2.3.0/app/Hooks/Handlers/AuthHandler.php#L149","https://plugins.trac.wordpress.org/browser/fluent-support/tags/2.3.0/app/Hooks/Handlers/AuthHandler.php#L201","https://plugins.trac.wordpress.org/browser/fluent-support/tags/2.3.0/app/Hooks/Handlers/AuthHandler.php#L500","https://plugins.trac.wordpress.org/browser/fluent-support/tags/2.3.0/app/Hooks/Handlers/AuthHandler.php#L111","https://plugins.trac.wordpress.org/changeset?reponame=&old=3609122%40fluent-support&new=3609122%40fluent-support"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15665.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15665","state":"PUBLISHED","datePublished":"2026-07-24T06:51:58.346Z","dateUpdated":"2026-07-24T20:26:51.110Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-13T20:46:44.256Z"},"containers":{"cna":{"title":"Fluent Support <= 2.3.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'redirect-to' Shortcode Attribute","descriptions":[{"lang":"en","value":"The Fluent Support – Helpdesk & Customer Support Ticket System plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'redirect-to' Shortcode Attribute in all versions up to, and including, 2.3.0 due to insufficient input sanitization and output escaping.
