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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":34,"depthScoreParts":{"impact":33.6,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
