Name of the Vulnerable Software and Affected Versions The (Simply) Guest Author Name plugin for WordPress versions up to, and including, 4.34

Description The issue is related to Stored Cross-Site Scripting via the plugin's post meta 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, 4.34, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting contributor-level and above permissions to minimize the risk of exploitation.
