CVE-2025-6024Network attack vector

Browser script execution via unencoded authentication input

Published Apr 16, 2026 · Updated Apr 16, 2026

Reflected XSS in affected WSO2 API Manager and Identity Server releases allows remote attackers to run script in a user's browser. The authentication endpoint renders user-supplied input without output encoding, turning a crafted request value into executable browser content. A victim must open the crafted request; script can redirect the browser, alter the page, or read browser-accessible data, but HttpOnly session cookies prevent session hijacking.
