What the vulnerability does
01Description
The Infomaniak Connect for OpenID plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'endpoint_login' parameter of the infomaniak_connect_generic_auth_url shortcode in all versions up to, and including, 1.0.2 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.
