Name of the Vulnerable Software and Affected Versions JHipster generator-jhipster versions prior to 2.23.0

Description The issue allows for a timing attack against the validateToken function due to a string comparison that stops at the first different character. This enables attackers to guess tokens through brute force, one character at a time, by observing the timing. The search space is reduced to a linear amount of guesses based on the token length times the possible characters.

Recommendations For versions prior to 2.23.0, update to version 2.23.0 or later to resolve the issue. As a temporary workaround, consider implementing a constant-time comparison for the validateToken function to prevent timing attacks.
