CVE-2024-3509

Stored script execution via unsanitized registry rich text

Published Jun 2, 2025 · Updated Jun 2, 2025

Stored XSS in the registry Rich Text Editor of affected WSO2 products allows remote authenticated users to run scripts in other users' browsers. The registry UI rendered saved rich-text content without sanitization; the public fix applies DOMPurify before rendering that content. Administrative Management Console access and another user's viewing of the stored content are required, while httpOnly cookies prevent session hijacking.
