Summary
MendixSSO <= 2.1.1 contains endpoints that make use of the openid handler, which is suffering from a Cross-Site Scripting vulnerability via the URL path. This is caused by the reflection of user-supplied data without appropriate HTML escaping or output encoding. As a result, a JavaScript payload may be injected into the above endpoint causing it to be executed within the context of the victim's browser.
Exploit prediction
0.72% chance of exploitation in the next 30 days, higher than 54% of all scored CVEs (FIRST EPSS, 2026-11-08).
