Executive brief
Worklenz is a project management platform that organizes tasks and team workflows. The application fails to properly validate user-supplied sorting parameters in pagination requests, allowing authenticated users to inject malicious SQL code. Attackers can exploit this to extract sensitive database information including password hashes from other tenants, compromising data confidentiality and customer isolation in a multi-tenant environment.
Technical details
The vulnerability is a SQL injection flaw in the pagination helper function's sort-field parameter validation. The vulnerable code directly interpolates user-controlled sortField and sortOrder values into ORDER BY clauses without proper sanitization (e.g., `ORDER BY ${sortField} ${sortOrder}`). Exploitation requires authentication but no additional preconditions; attackers can inject arbitrary PostgreSQL expressions such as time-based or boolean-based blind SQL injection to exfiltrate data from the database. This is categorized as an incomplete fix for the prior CVE-2026-25947. Patches should implement a whitelist of allowed sort fields and parameterize sort order as an enumerated value.
