VNX-GH-006 – Release workflow restores a cache writable by untrusted runs

Overview

Caches are shared across workflows in the same branch scope. A compromised or injectable workflow on the default branch can save a poisoned cache entry that a release workflow later restores and ships inside a published artifact.

Severity: High | Confidence: medium | CWE: CWE-349, CWE-494 | Command: vulnetix gha workflows

Mappings: T1195.002

Remediation

Disable caching in workflows that publish releases or sign artifacts (remove cache: / actions/cache), or use a cache key namespace no other workflow writes.
