What is CVE-2026-110118?

WorkFlow-Engine versions through 9.6.11 are impacted by a vulnerability that facilitates unauthorized access to workflow tasks for authenticated users. The flaw arises from the /vue/buttonOperation endpoints, where low-privileged attackers can exploit a known taskId in the complete, completeTask, or reAssign handlers. This allows them to approve or reassign tasks without proper authorization, potentially compromising workflow integrity and control.

Affected Version(s)

WorkFlow-Engine 0 <= 9.6.11
