Input validation vulnerability in UMich OIDC Login 1.2.0

The UMich OIDC Login plugin for WordPress has a security issue called Stored Cross-Site Scripting. This is because the plugin does not properly clean up and protect user-provided information in its ‘umich_oidc_button’ feature. As a result, attackers who are logged in with contributor-level access or higher can insert harmful web scripts into pages. These scripts will run whenever a user visits the affected page.
