CVE-2026-8198
Activity Logs, User Activity Tracking, Multisite Activity Log from Logtivity <= 3.3.6 - Unauthenticated Information Disclosure via REST API
Description
The Activity Logs, User Activity Tracking, Multisite Activity Log from Logtivity plugin for WordPress is vulnerable to Authentication Bypass to Information Disclosure in versions up to, and including, 3.3.6. This is due to a logic flaw in the verifyAuthorization method where requests without an Authorization header skip Bearer token validation and fall through to an unconditional return true statement, bypassing all authentication checks. This makes it possible for unauthenticated attackers to access the /wp-json/logtivity/v1/options REST API endpoint and retrieve all plugin configuration options, including the logtivity_site_api_key which can be used to impersonate the site in API calls to the Logtivity service.
