CVE-2026-82546Apache Roller: Stored cross-site scripting through incoming Trackback links
Medium 6.1
In plain English
A medium-severity cross-site scripting in Apache Roller from Apache Software Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 20% of all known vulnerabilities).
Official 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.
