Summary
The Lockme OAuth2 calendars integration plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'App ID' setting in versions up to and including 2.11.0. Insufficient input sanitization and output escaping allow unsanitized data to be stored and echoed without proper encoding on the settings page. Authenticated attackers with administrator-level access can inject arbitrary scripts that execute whenever the plugin settings page is accessed.
Risk Assessment
The risk involves potential execution of malicious JavaScript by site administrators in WordPress multisite installations, which could lead to session theft, content modification, or privilege escalation affecting other users.
Recommendation
Immediately update the Lockme OAuth2 calendars integration plugin to the latest available version that includes security fixes. If no update is available, temporarily disable the plugin or restrict access to the settings page to trusted administrators only.

Original NVD description (English source)
The Lockme OAuth2 calendars integration plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'App ID' setting in all versions up to, and including, 2.11.0. This is due to insufficient input sanitization and output escaping. The register_setting() call on line 197 lacks a sanitize callback, allowing unsanitized data to be stored via update_option(). When the settings page is rendered, the stored value is echoed directly into an HTML input's value attribute without esc_attr() on line 212. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in the settings page that will execute whenever a user accesses the plugin settings page. Multiple fields are affected: App ID (client_id), App Secret (client_secret), Bookings ID prefix (id_prefix), and API domain (api_domain). This vulnerability is particularly impactful in WordPress multisite installations where administrators of individual sites should not be able to execute JavaScript affecting other users.
