CVE-2025-13910

Name of the Vulnerable Software and Affected Versions WP-WebAuthn plugin for WordPress versions up to and including 1.3.4

Description The WP-WebAuthn plugin for WordPress is susceptible to Unauthenticated Stored Cross-Site Scripting through the wwa auth API endpoint. This is due to inadequate input sanitization and output escaping of user-supplied attributes when the plugin logs data. An unauthenticated attacker can inject arbitrary web scripts into pages, which will execute when a user accesses the plugin’s log page, provided logging is enabled in the plugin settings.

Recommendations Update the WP-WebAuthn plugin to a version later than 1.3.4.
