CVE-2024-11753 Information

Description

The UMich OIDC Login plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin’s ‘umich_oidc_button’ shortcode in all versions up to and including 1.2.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
