{"id":"CVE-2026-82546","published":"2026-09-28T08:16:42.763","lastModified":"2026-09-28T14:29:44.860","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.","cvssScore":6.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/apache/roller/pull/178","tags":[]},{"url":"https://lists.apache.org/thread/ddrykzvs67zpmzwsbqyfjmlydboln8x1","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/09/25/21","tags":[]}],"exploitRefs":[{"url":"https://github.com/apache/roller/pull/178","tags":[]}],"hasPoc":true,"ai":null}
