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.","state":0,"publishedAt":"2026-09-28T07:35:38.234+00:00","modifiedAt":"2026-09-30T11:41:21.436+00:00","affected":[{"ecosystem":"Vendor product","name":"Apache Roller","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache Roller\",\n                    \"repo\": \"https://github.com/apache/roller\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"6.1.5\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unknown\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1,"severity":"MEDIUM"}],"references":["https://github.com/apache/roller/pull/178","https://lists.apache.org/thread/ddrykzvs67zpmzwsbqyfjmlydboln8x1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-82546","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-82546","identifiers":["CVE-2026-82546"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
