CVE-2026-82546

Description

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 6.1.5 allows an unauthenticated remote attacker to store a crafted comment-author URL through the incoming Trackback endpoint when a published entry accepts comments and Trackbacks. The shipped Trackback, verification and moderation defaults allow the value to be approved and rendered as an active link; a visitor who clicks the link executes script in the weblog's origin. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which removes incoming Trackback support and suppresses non-HTTP(S) comment-author links. Users unable to upgrade should disable Trackbacks and remove untrusted Trackback comments.
