CVE-2025-13730: Daggerhart Openid Connect Generic Client

Medium severity, CVSS 6.4. EPSS: 0.2% chance of exploitation in the next 30 days.

The OpenID Connect Generic Client plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'openid_connect_generic_auth_url' shortcode in all versions up to, and including, 3.10.0 due to insufficient input sanitization and output escaping. This makes it possible for 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.

Affected products

• Daggerhart Openid Connect Generic Client: up to and including 3.10.0
