{"id":"CVE-2026-91204","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.","modified":"2026-10-02T03:31:06.143082641Z","published":"2026-09-28T07:34:33.187Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/91xxx/CVE-2026-91204.json","cna_assigner":"apache","cwe_ids":["CWE-79"]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/09/25/23"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/91xxx/CVE-2026-91204.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/4qzp8m0438056l5t6m6719ob79gx72lz"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-91204"},{"type":"FIX","url":"https://github.com/apache/roller/pull/190"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/roller","events":[{"introduced":"395cfa30a7b274f8540424d11404c3e7433243f8"},{"last_affected":"395cfa30a7b274f8540424d11404c3e7433243f8"}],"database_specific":{"extracted_events":[{"introduced":"6.1.5"},{"last_affected":"6.1.5"}],"source":"AFFECTED_FIELD"}}],"versions":["6.1.5","roller-6.1.5"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-91204.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"}]}
