{"schema_version": "1.6.1", "id": "CVE-2026-91204", "summary": "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.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "6.1.5"}, {"last_affected": "6.1.5"}]}]}], "references": [{"type": "WEB", "url": "https://github.com/apache/roller/pull/190"}, {"type": "WEB", "url": "https://lists.apache.org/thread/4qzp8m0438056l5t6m6719ob79gx72lz"}]}
