CVE-2024-9421

Name of the Vulnerable Software and Affected Versions Login Logout Shortcode plugin for WordPress versions up to, and including, 1.1.0

Description The issue is related to Stored Cross-Site Scripting via the class 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 versions up to, and including, 1.1.0, consider disabling the class parameter until a patch is available to prevent exploitation. Restrict access to the plugin's functionality to minimize the risk of arbitrary web script injection. As a temporary workaround, limit Contributor-level access and above to reduce the potential for malicious activity. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
