CVE-2026-65565Network attack vector

Reflected XSS via unsanitized survey submissions

Published Aug 6, 2026 · Updated Aug 6, 2026

Reflected cross-site scripting in AYS Pro Survey Maker 5.2.3.3 and earlier allows remote attackers to execute scripts through survey submissions. The 5.2.3.4 changelog identifies deficient sanitization and response handling in the submission path, while public materials omit the affected parameter and function. Successful exploitation is unauthenticated but requires a privileged user to open a crafted link or page or submit a form, causing attacker-supplied script to run in that user's browser.
