A flaw was found in pnpm, a package manager. This vulnerability allows a remote attacker to achieve arbitrary code execution by committing a specially crafted package-manager lockfile (`pnpm-lock.yaml`) to a repository. When pnpm is executed, it trusts an already resolved `packageManagerDependencies` entry, enabling the malicious lockfile to bypass standard package resolution. This can cause pnpm to install and execute attacker-controlled code during automatic version switching. pnpm: pnpm: Arbitrary code execution via malicious package-manager lockfile This is an Important arbitrary code execution flaw in pnpm, a package manager used in Red Hat products. The vulnerability arises from pnpm's trust in pre-resolved package manager metadata within `pnpm-lock.yaml`, allowing a malicious repository to bypass standard package resolution. This can lead to the execution of attacker-controlled code when pnpm is used to install dependencies from such a repository, posing a significant supply chain risk. The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
