Affected packages

• npm buttle: all versions (no fix yet)

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