Summary

An attacker who has permission to create a repository in Bamboo, edit an existing plan in Bamboo that has a non-linked Mercurial repository, or create a plan in Bamboo either globally or in a project using Bamboo Specs can can execute code of their choice on systems that run a vulnerable version of Bamboo on the Windows operating system. All versions of Bamboo starting with 2.7.0 before 6.3.3 (the fixed version for 6.3.x) and from version 6.4.0 before 6.4.1 (the fixed version for 6.4.x) running on the Windows operating system are affected by this vulnerability.
