Technical details
This is an authorization bypass vulnerability in Worklenz's task-scoped API endpoints. The application fails to verify task ownership against the authenticated user's organization when processing requests to task-related endpoints. An authenticated attacker can craft requests with arbitrary task UUIDs to retrieve sensitive data (work logs, comments, attachments, project insights) belonging to other tenants. The vulnerability requires authentication but no special privileges, and the fix is available in version 3.0.0 and later via a verify-task-access middleware implementation.
