Reflected XSS via unsanitized authentication input
Published Apr 16, 2026 · Updated Apr 16, 2026
Reflected XSS in WSO2 API Manager 3.2.0 and 4.0.0 allows remote attackers to execute script via crafted authentication input. The authentication endpoint reflects insufficiently validated input into its response, causing the victim's browser to execute an injected script. Exploitation requires a victim to open the crafted request; it can redirect the browser, alter the page, or expose browser data, but httpOnly cookies block reported session theft.
