Name of the Vulnerable Software and Affected Versions The Blog Filter plugin for WordPress versions up to, and including, 1.4

Description The issue is related to Stored Cross-Site Scripting via the 'vivafbcomment' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. 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, 1.4, consider disabling the 'vivafbcomment' shortcode until a patch is available to prevent exploitation. Restrict access to pages that use this shortcode to minimize the risk of arbitrary web script injection. Ensure proper input sanitization and output escaping for all user-supplied attributes to prevent similar issues in the future.
