{"id":"CVE-2026-103370","kind":"vulnerability","aliases":["CVE-2026-103370"],"related":[],"title":"Awesome Support WordPress plugin: stored XSS via ticket file uploader","description":"The Awesome Support – WordPress HelpDesk & Support Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wpas_files' parameter in all versions up to, and including, 6.4.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability is only exploitable when the \"Enable drag-n-drop uploader for ticket form\" setting is enabled, as it is disabled by default.","summary":"Awesome Support, a WordPress helpdesk plugin, does not sanitize the wpas_files parameter, so text saved there is later rendered as script.
