New CVE NOT AVAILABLE CWE-352  (opens in a new tab)

How to fix?

Upgrade label-studio-sso to version 6.0.3 or higher.

Overview

label-studio-sso is a Native JWT authentication for Label Studio OSS - simple and secure SSO integration

Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF) due to an improper exemption in the JWTSSOSessionAuthentication mechanism that disables CSRF token validation. An attacker can exploit this by crafting malicious cross-site requests that trigger privileged actions in the application using the victim’s authenticated session, allowing unauthorized operations to be performed without the user’s consent.
