CVE-2023-37581Network attack vector

Cross-site scripting via unsanitized weblog content

Published Aug 6, 2023 · Updated Oct 1, 2024

Cross-site scripting in Apache Roller before 6.1.2 allows remote authenticated users to execute script in another user's browser. Weblog category names, Website About text, and file uploads are accepted without sufficient input validation and sanitization before their content is rendered. Exposure requires a group-blog site that permits untrusted authors, plus a victim who views the crafted content in the Roller origin.
