Detailsinfo

A vulnerability was found in ProcessMaker up to 2026.14.2. It has been rated as critical. This issue affects the function ProcessMaker\Traits\TaskControllerIndexMethods::applyColumnOrdering of the component Column Ordering. The manipulation of the argument order_by with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

ProcessMaker is an open source workflow management software suite. Prior to 2026.14.3, the `GET /api/1.0/tasks` endpoint in ProcessMaker is vulnerable to SQL injection through the order_by parameter because `ProcessMaker\Traits\TaskControllerIndexMethods::applyColumnOrdering()` concatenates a user-controlled process_requests column name into a DB::raw() SQL subquery without validation or parameter binding. Any authenticated user can use blind, time-based queries to infer and extract data accessible to the ProcessMaker database account. This issue is fixed in version 2026.14.3.
