Name of the Vulnerable Software and Affected Versions Breakdance plugin for WordPress versions up to, and including, 1.7.0

Description The issue is related to Stored Cross-Site Scripting via the plugin's custom postmeta output due to insufficient input sanitization and output escaping on user-supplied post meta fields. This allows authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 1.7.0, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the custom postmeta output feature until a patch is available. Additionally, restrict permissions to prevent contributors and above from injecting malicious scripts.
