SCA: security update for org.apache.shiro:shiro-core (GHSA-c4qc-4q9p-m9q9)
low Tenable Self-Hosted Container Security Plugin ID 437682
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Observable Timing Discrepancy vulnerability in Apache Shiro. This issue affects Apache Shiro: from 1.*,
2.* before 2.0.7. Users are recommended to upgrade to version 2.0.7 or later, which fixes the issue. Prior
to Shiro 2.0.7, code paths for non-existent vs. existing users are different enough, that a brute-force
attack may be able to tell, by timing the requests only, determine if the request failed because of a non-
existent user vs. wrong password. The most likely attack vector is a local attack only. Shiro security
model https://shiro.apache.org/security-model.html#username_enumeration discusses this as well. Typically,
brute force attack can be mitigated at the infrastructure level. (CVE-2026-23901)
