{"schema":"threatline.record/2","record":{"id":"CVE-2026-82546","aliases":[],"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.","categories":["Unclassified"],"product":"Apache Roller","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-82546","source_modified_at":"2026-09-30T11:41:21.436Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Apache Roller","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"6.1.5","versionType":"semver"}],"defaultStatus":"unknown"}],"fixed_versions":[],"cvss":6.1,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00276,"percentile":0.18974,"score_date":"2026-10-23"},"published_at":"2026-09-28T07:35:38.234Z","modified_at":"2026-09-30T11:41:21.436Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-82546","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T11:41:21.436Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-82546","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/apache/roller/pull/178","tags":["patch"]},{"source":"CVE List","url":"https://lists.apache.org/thread/ddrykzvs67zpmzwsbqyfjmlydboln8x1","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-30T11:39:32.713189Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T11:41:21.436Z","content_hash":"4cd2d47d48ac88ae86aaf7cd2fe2e26b9ef3de6de82a99e45db89f31c5ded385"}}
