# CVE-2026-118413: Apache Roller: Stored cross-site scripting through imported blogroll links

Status: published. Published: 2026-11-11. Updated: 2026-11-11.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 4.0 through 6.1.6 allows a weblog administrator to store script that runs in the browsers of the weblog's visitors. Blogroll links imported from an OPML file were not checked, and the default theme printed them without escaping. Users are recommended to upgrade to Apache Roller 6.1.7 or later, which accepts only web links on import and escapes them on output.
