Browser script execution via unencoded reflected input
Published Jul 18, 2023 · Updated Apr 28, 2026
Reflected XSS in CodePeople Booking Calendar Contact Form 1.2.40 and earlier allows remote attackers to execute script via crafted requests. The plugin returns attacker-controlled request data to a generated page without sufficient output encoding; public records do not identify the affected parameter or code locus. No account is required, but exploitation requires a privileged user to follow a crafted link or otherwise submit the malicious request, allowing script execution in that user's browser context.
