Reflected XSS via unsanitized URL parameters
Published Jul 13, 2026 · Updated Jul 13, 2026
Reflected XSS in CRM Perks Forms 1.1.7 and earlier allows remote attackers to execute script in a visitor's browser via a crafted URL. The plugin reflects URL-parameter input into generated page content without sufficient neutralization; the vendor has not identified the affected parameter or code path. Exploitation is unauthenticated but requires a visitor to open the crafted URL, allowing attacker-controlled script to run in that visitor's browser context.
