CVE-2026-91206

Summary

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 6.1.5 allows a remote attacker to perform reflected cross-site scripting through the optional LDAP comment authenticator, which writes request parameter values into its HTML form without escaping. This affects only sites configured to use LdapCommentAuthenticator, and a victim whose session has already loaded the authenticator form must follow a crafted link. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which escapes the reflected values.
