Name of the Vulnerable Software and Affected Versions pnpm versions prior to 10.34.0 pnpm versions prior to 11.4.0 Description pnpm may send user-level unscoped npm authentication credentials to a registry specified in a repository-local .npmrc file. This occurs when a user's global configuration...

CVE-2026-55180: Exposure of Sensitive Information to an Unauthorized Actor

pnpm is a package manager. Prior to 10.34.2 and 11.5.3, pnpm and pacquet expanded $ENVVAR placeholders from repository-controlled .npmrc and pnpm-workspace.yaml into registry request destinations and registry credentials. A malicious repository could cause dependency resolution to send victim...

CVE-2026-55697: Improper Neutralization of Special Elements used in an OS Command

pnpm is a package manager. Prior to 10.34.2 and 11.5.3, pnpm can install configDependencies declared in pnpm-workspace.yaml before command dispatch. Before the patch, a repository could declare pacquet or @pnpm/pacquet as a config dependency and pnpm treated that repository-controlled dependency ...

CVE-2026-55700: Improper Limitation of a Pathname to a Restricted Directory

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,...

Name of the Vulnerable Software and Affected Versions pnpm versions 11.3.0 through 11.5.2 Description The pnpm stage download command derives a local filename using package name and version fields controlled by the registry. A crafted manifest can lead to a path traversal, allowing an attacker to...

CVE-2026-55487: Origin Validation Error

pnpm is a package manager. Prior to 10.34.2 and 11.5.3, the generic peer-suffix normalizer also stripped parenthesized text from git, URL, tarball, file, and other opaque locators. Approval for one source string could therefore authorize a different attacker-controlled source whose locator...

CVE-2026-50014: Improper Neutralization of Argument Delimiters in a Command

pnpm is a package manager. Prior to 10.34.0 and 11.4.0, pnpm passes the lockfile-controlled git resolution.commit value to git fetch without a -- separator or commit-format validation. For git dependencies fetched through the shallow-fetch path, a malicious lockfile can replace the expected...

CVE-2026-50017: Exposure of Sensitive Information to an Unauthorized Actor

pnpm is a package manager. Prior to 10.34.0 and 11.4.0, pnpm can send user-level unscoped npm authentication credentials to a registry chosen by a repository-local .npmrc file. In the reproduced case, the user's npm config contains a default registry and an unscoped authToken. The repository does...

CVE-2026-50021: Improper Validation of Integrity Check Value

pnpm is a package manager. Prior to 10.34.0 and 11.4.0, pnpm's tarball extraction worker skips integrity verification when the integrity field is absent from the lockfile resolution. If an attacker can both modify pnpm-lock.yaml to remove the integrity: field and cause the referenced registry URL...

Name of the Vulnerable Software and Affected Versions pnpm versions prior to 10.34.2 pnpm versions 11.0.0 through 11.5.2 Description pnpm can persist package-manager bootstrap metadata in the first YAML document of the pnpm-lock.yaml file. The issue occurs when pnpm incorrectly trusts an already...

CVE-2026-50015: Improper Limitation of a Pathname to a Restricted Directory

pnpm is a package manager. Prior to 10.34.0 and 11.4.0, pnpm's patch application pipeline @pnpm/patch-package performs no path validation on file paths extracted from .patch files. An attacker who contributes a malicious patch file via a pull request can write attacker-controlled content to or...

CVE-2026-55699: Improper Limitation of a Pathname to a Restricted Directory

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...

Name of the Vulnerable Software and Affected Versions pnpm versions prior to 10.34.2 pnpm versions prior to 11.5.3 Description Manifest bin object keys such as "", ".", and ".." bypass the bin-name guard. If a malicious package is installed globally, subsequent global remove, update, or...

CVE-2026-48995: Missing Support for Integrity Check

pnpm is a package manager. Prior to 10.33.4 and 11.0.7, a malicious codeload.github.com server can serve whatever tarball it wants and pnpm will install it regardless of the lockfile. The lockfile does not store the hash of the dependencies from https://codeload.github.com. This means that if thi...

CVE-2026-50016: Relative Path Traversal

pnpm is a package manager. Prior to 10.34.0 and 11.4.0, pnpm allows a transitive dependency alias from registry package metadata to contain path traversal segments. During install, pnpm later uses that alias as a filesystem path when linking dependency nodes. As a result, a registry package can...

CVE-2026-50573: Insufficient Verification of Data Authenticity

pnpm is a package manager. Prior to 10.34.0 and 11.4.0, pnpm install in non-frozen mode can accept new remote package content after detecting that the downloaded tarball does not match the integrity recorded in pnpm-lock.yaml. When a package is already locked with an integrity value, and the...
