Subscriber sync and log deletion via exposed nonce
Published Aug 12, 2026 · Updated Aug 12, 2026
Missing authorization in ProSolution WP Client before 2.0.9 allows remote authenticated users to synchronize data and clear activity records. The proSol_ajaxTablesync and proSol_ajaxClearlog handlers verify a frontend-published nonce but omit capability checks before truncating and resynchronizing plugin tables or deleting activity-log rows. Subscriber access and a public job-portal page expose the required nonce; exploitation alters synchronized data and removes the selected site's activity history.
