Name of the Vulnerable Software and Affected Versions WordPress Social Login plugin for WordPress versions up to, and including, 3.0.4

Description The issue is related to Stored Cross-Site Scripting via the 'wordpress social login meta' 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 WordPress Social Login plugin for WordPress versions up to, and including, 3.0.4, consider updating to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the 'wordpress social login meta' shortcode for users with contributor-level and above permissions to minimize the risk of exploitation.
