Users are recommended to upgrade to Apache Roller 6.1.6 or later.
AI Analysis
Technical Summary
Apache Roller 6.1.5 suffers from an improper neutralization of input vulnerability (CWE-79) that permits an anonymous remote attacker to store a malicious comment-author URL.

This vulnerability requires no special server settings and affects any site permitting comments on weblogs with moderator review. The vulnerability is addressed by upgrading to version 6.1.6 or later.
Potential Impact
An attacker can execute arbitrary scripts in the context of a weblog moderator or global administrator session by injecting malicious URLs in comment-author fields.
