{"schemaVersion":3,"id":"CVE-2026-91204","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"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.","dates":{"published":"2026-09-28T07:34:33.187Z","modified":"2026-09-30T11:39:14.237Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.1,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00396,"percentile":0.32193,"severity":"low","asOf":"2026-10-18T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-09-28T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00396,"percentile":0.32193}],"last30":[{"date":"2026-09-28T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00396,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00396,"percentile":0.32193}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-79","name":"Improper
