CVE-2026-91025: CWE-639 Authorization Bypass Through User-Controlled Key in Booking Manager
The Booking Manager WordPress plugin before 2.1.21 does not verify that a request to modify a user's Booking Manager WordPress plugin before 2.1.21-specific settings targets the requesting user's own account, allowing any authenticated user with subscriber-level access and above to create or overwrite the Booking Manager WordPress plugin before 2.1.21's per-user settings on arbitrary users, including administrators.
AI Analysis
Technical Summary
CVE-2026-91025 is an authorization bypass vulnerability in the Booking Manager WordPress plugin versions prior to 2.1.21. The plugin fails to verify that requests to modify user-specific settings are restricted to the requesting user's own account. Consequently, authenticated users with subscriber-level access or above can create or overwrite per-user settings for any user, including administrators, potentially leading to unauthorized configuration changes.
Potential Impact
Authenticated users with minimal privileges can alter settings of other users, including administrators, which may lead to privilege escalation or unauthorized changes in the plugin's behavior. This undermines the integrity of user-specific configurations and could facilitate further attacks depending on the plugin's role in the WordPress environment.
Mitigation Recommendations
Upgrade the Booking Manager WordPress plugin to version 2.1.21 or later, where this authorization bypass vulnerability is fixed. No other mitigation steps are indicated by the available data.
