CVE-2024-5848Network attack vector

Reflected XSS via unencoded service response

Published Feb 27, 2025 · Updated Feb 27, 2025

Reflected XSS in affected WSO2 API Manager and Open Banking AM releases allows remote attackers to run JavaScript in a user's browser. The deployed OpenService Synapse API returns user-controlled data in its response without validation, sanitization, or output encoding. Exploitation requires a user to follow a crafted request; gateway restrictions can block the endpoint, and httpOnly cookies limit session theft.
