{"id":"CVE-2026-82546","summary":"Apache Roller: Stored cross-site scripting through incoming Trackback links","details":"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.","modified":"2026-10-01T03:31:04.854608284Z","published":"2026-09-28T07:35:38.234Z","database_specific":{"cna_assigner":"apache","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82546.json"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/09/25/21"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82546.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/ddrykzvs67zpmzwsbqyfjmlydboln8x1"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-82546"},{"type":"FIX","url":"https://github.com/apache/roller/pull/178"},{"type":"PACKAGE","url":"https://github.com/apache/roller"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/roller","events":[{"introduced":"395cfa30a7b274f8540424d11404c3e7433243f8"},{"last_affected":"395cfa30a7b274f8540424d11404c3e7433243f8"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"6.1.5"},{"last_affected":"6.1.5"}]}}],"versions":["6.1.5","roller-6.1.5"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-82546.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
