CVE-2026-55700

pnpm stage download (affecting 11.3.0–11.5.3) allowed a crafted manifest to derive a local filename from package name and version, enabling the download to escape the target directory and overwrite a reachable file. The merged fix validates both fields, derives a single safe filename, and verifie...

CVE-2026-55700 pnpm: stage download writes outside destination via manifest version traversal

pnpm is a package manager. From 11.3.0 until 11.5.3, pnpm stage download derived a local filename from registry-controlled package name and version fields. A crafted manifest could escape the selected download directory and overwrite another reachable file. The merged fix validates both fields,...

CVE-2026-55699

pnpm is a package manager. Prior to 10.34.2 and 11.5.3, Manifest bin object keys such as "", ".", and ".." passed pnpm's bin-name guard. When a malicious package was installed globally, later global remove, update, or add-replacement flows could re-derive those names from the installed manifest a...

CVE-2026-55699 affects pnpm. Prior to versions 10.34.2 and 11.5.3, manifest bin object keys such as "", ".", and ".." could bypass the bin-name guard. In a scenario where a malicious global package is installed, downstream global remove/update/add-replacement flows could re-derive those names and...

CVE-2026-55698

pnpm is a package manager. Prior to 10.34.2 and 11.5.3, pnpm can persist package-manager bootstrap metadata in the first YAML document of pnpm-lock.yaml. Before the patch, direct pnpm execution trusted an already resolved packageManagerDependencies entry when the committed env lockfile contained...

CVE-2026-55698

pnpm advisory (CVE-2026-55698) affects pnpm by allowing a crafted env lockfile in pnpm-lock.yaml to bypass fresh package-manager resolution and cause installation of bytes selected by the lockfile state. The issue occurs prior to 10.34.2 and 11.5.3, which have fixed the vulnerability. The vulnera...

CVE-2026-55697

pnpm is vulnerable prior to 10.34.2 and 11.5.3: repository‑controlled configDependencies in pnpm-workspace.yaml could cause pnpm to install a repository‑controlled install‑engine (pacquet) by resolving a platform‑specific @pacquet/-/pacquet binary from node_modules/.pnpm-config and spawning it as...
