{"id":"CVE-2026-91206","summary":"Apache Roller: Reflected XSS in the optional LDAP comment authenticator","details":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 6.1.5 allows a remote attacker to perform reflected cross-site scripting through the optional LDAP comment authenticator, which writes request parameter values into its HTML form without escaping. This affects only sites configured to use LdapCommentAuthenticator, and a victim whose session has already loaded the authenticator form must follow a crafted link. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which escapes the reflected values.","modified":"2026-10-02T03:30:42.726064958Z","published":"2026-09-28T07:33:13.837Z","database_specific":{"cna_assigner":"apache","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/91xxx/CVE-2026-91206.json"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/09/25/24"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/91xxx/CVE-2026-91206.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/tljwqdttq8tgg6hr8sxlcnwpxl6pch4s"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-91206"},{"type":"FIX","url":"https://github.com/apache/roller/pull/191"}],"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-2026-91206.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"}]}
