{"schema":"threatline.record/2","record":{"id":"CVE-2026-91204","aliases":[],"summary":"Apache Roller: Stored javascript: URI in HTML comments","details":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 6.1.5 allows an anonymous remote attacker to store a comment containing a javascript: URI link that survives HTML comment formatting and can execute script in the browser of a visitor who clicks it. This affects only sites that enable HTML in comments (users.comments.htmlenabled=true) together with the HTMLSubset comment formatter; comment moderation, where enabled, delays publication. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which restricts restored links to http, https and mailto URIs.","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-2026-91204","source_modified_at":"2026-09-30T11:39:14.237Z","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":0.00396,"percentile":0.32602,"score_date":"2026-10-23"},"published_at":"2026-09-28T07:34:33.187Z","modified_at":"2026-09-30T11:39:14.237Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-91204","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T11:39:14.237Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-91204","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/190","tags":["patch"]},{"source":"CVE List","url":"https://lists.apache.org/thread/4qzp8m0438056l5t6m6719ob79gx72lz","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":"2026-09-30T11:39:04.573954Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T11:39:14.237Z","content_hash":"bcb9da297b5665a9c75e3c777f5b0aad945aa11c7a4bc2ef8decf567f2a9a8f8"}}
