Last modified

CVE-2025-30064 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. An insufficiently secured internal function allows session generation for arbitrary users. The decodeParam function checks the JWT but does not verify which signing algorithm was used. EPSS estimates a 0.08% chance of exploitation in the next 30 days.

Description

An insufficiently secured internal function allows session generation for arbitrary users. The decodeParam function checks the JWT but does not verify which signing algorithm was used. As a result, an attacker can use the "ex:action" parameter in the VerifyUserByThrustedService function to generate a session for any user.
