CVE-2025-66036Network attack vector

Browser-side script execution via unsanitized input

Published Nov 29, 2025 · Updated Dec 1, 2025

Cross-site scripting in Anjaliavv51 Retro before 2.4.7 allows remote attackers to run browser-side JavaScript via crafted input. The scriptsignup.js input-handling component processes user-provided content without adequate sanitization or output encoding, but the advisory identifies no function, parameter, or patch diff. Exploitation requires a user to interact with affected content and exposes that user's session or credentials to browser-side script access without interrupting the service.
