CVE-2026-14439Network attack vector

Authenticated code execution via unchecked post-clone paths

Published Jul 1, 2026 · Updated Jul 1, 2026

Path traversal in the Git Service in Altium Enterprise Server and Altium 365 allows remote authenticated users to execute code. The CloneRepository action accepts post-clone file-move operations and uses user-supplied paths without validating that destinations remain inside the repository area. Basic Git access is sufficient to plant attacker-controlled scripts for execution as the Git Service account, exposing co-resident tenant data in multi-tenant cloud deployments.
