Technical details

A path traversal vulnerability (CWE-22) exists in the Git Service component due to a lack of validation on user-supplied paths during post-clone file-manipulation operations. An authenticated attacker with basic Git access can exploit this 'file-move primitive' to place malicious scripts into executable directories, leading to remote code execution (CWE-94) under the service account. In multi-tenant Altium 365 environments, this flaw could be used to bypass tenant isolation and access data belonging to other customers. Altium Enterprise Server users should upgrade to version 8.1.1, while Altium 365 has been patched at the service level.

Affected products

Altium Enterprise Server versions prior to 8.1.1
