CVE-2025-36852Public exploitNetwork attack vector

Artifact injection via shared cache namespace

Published Jun 10, 2025 · Updated Jun 10, 2025

Build cache poisoning in affected Nx remote-cache plugins allows remote authenticated users to inject artifacts into trusted builds. The plugins let pull-request and protected-branch jobs write the same cache key, and the first artifact stored becomes the trusted result. Pull-request privileges and a shared writable remote-cache namespace are required; a poisoned artifact can execute when a trusted build consumes it.
