CVE-2015-20110

CWE-307Published: October 31, 2023· Updated: Jun 17, 2026

7.5
CVSS v3.1

Official Description

JHipster generator-jhipster before 2.23.0 allows a timing attack against validateToken due to a string comparison that stops at the first character that is different. Attackers can guess tokens by brute forcing one character at a time and observing the timing. This of course drastically reduces the search space to a linear amount of guesses based on the token length times the possible characters.
