Description

All versions of buttle are vulnerable to Cross-Site Scripting. Due to misconfiguration of its rendering engine, buttle does not sanitize the HTML output allowing attackers to run arbitrary JavaScript when processing malicious markdown files.

No fix is currently available. Consider using an alternative module until a fix is made available.
