CVE-2026-19052: CWE-862 Missing Authorization in ProSolution WP Client
The ProSolution WP Client WordPress plugin before 2.0.9 does not perform capability checks on two administrative AJAX actions, and the nonce they rely on is published on its public frontend, allowing any authenticated user, such as a subscriber, to trigger an administrative data synchronisation and to clear the ProSolution WP Client WordPress plugin before 2.0.9's activity records.
AI Analysis
Technical Summary
CVE-2026-19052 describes a missing authorization vulnerability (CWE-862) in the ProSolution WP Client WordPress plugin versions prior to 2.0.9. The plugin does not verify user capabilities on two administrative AJAX endpoints. Additionally, the nonce intended to protect these actions is exposed on the public frontend, enabling any authenticated user to invoke administrative functions improperly. This flaw allows unauthorized users to perform administrative data synchronization and clear activity logs, which should be restricted to privileged users.
Potential Impact
Unauthorized authenticated users, including subscribers, can execute administrative AJAX actions that synchronize data and clear activity records. This could lead to unauthorized modification or deletion of plugin data, potentially disrupting plugin functionality or tampering with audit trails.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict authenticated user roles to trusted users only and monitor for unusual activity related to the plugin's administrative AJAX actions.
