Name of the Vulnerable Software and Affected Versions: WP-WebAuthn plugin for WordPress versions up to, and including, 1.3.1

Description: The issue arises from insufficient input sanitization and output escaping on user-supplied attributes in the wwa login form shortcode. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages. These scripts will execute whenever a user accesses an injected page.

Recommendations: For versions up to, and including, 1.3.1, update to a version that addresses the insufficient input sanitization and output escaping issue in the wwa login form shortcode. As a temporary workaround, consider restricting access to the wwa login form shortcode to minimize the risk of exploitation.
