Name of the Vulnerable Software and Affected Versions Minimal Share Buttons plugin for WordPress versions up to, and including, 1.7.3

Description The issue is related to Stored Cross-Site Scripting via the align parameter due to insufficient input sanitization and output escaping. This allows authenticated attackers with Contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For Minimal Share Buttons plugin for WordPress versions up to, and including, 1.7.3, update to a version that includes the necessary input sanitization and output escaping to prevent Stored Cross-Site Scripting. As a temporary workaround, consider restricting access to the align parameter to minimize the risk of exploitation.
