CVE-2026-24056 is a medium-severity path traversal vulnerability in pnpm (npm), affecting versions < 10.28.2. It is fixed in 10.28.2.
Summary When pnpm installs a file: (directory) or git: dependency, it follows symlinks and reads their target contents without constraining them to the package root. A malicious package containing a symlink to an absolute path (e.g., /etc/passwd, ~/.ssh/idrsa) causes pnpm to copy that file's contents into nodemodules, leaking local data. Preconditions: Only affects file: and git: dependencies. Registry packages (npm) have symlinks stripped during publish and are NOT affected. Details The vulnerability exists in store/cafs/src/addFilesFromDir.ts. The code uses fs.statSync() and readFileSync() which follow symlinks by default: There is no check that absolutePath resolves to a location inside the package directory. PoC Impact Developers installing local/file dependencies CI/CD pipelines installing git dependencies Credential theft via symlinks to ~/.aws/credentials, ~/.npmrc, ~/.ssh/id_rsa Suggested Fix Use lstatSync to detect symlinks and reject those pointing outside the package root in store/cafs/src/addFilesFromDir.ts.
Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files. Typical impact: unauthorized file read or write outside the intended directory.
CVE-2026-24056 has a CVSS score of 6.5 (Medium). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment.
A fixed version is available (10.28.2). Upgrading removes the vulnerable code path.
npm
pnpm (< 10.28.2)pnpm → 10.28.2 (npm)Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.

CVE-2026-24056 is a medium-severity path traversal vulnerability in pnpm (npm), affecting versions < 10.28.2. It is fixed in 10.28.2. Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files.
CVE-2026-24056 has a CVSS score of 6.5 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
pnpm (npm) versions < 10.28.2 is affected.
Yes. CVE-2026-24056 is fixed in 10.28.2. Upgrade to this version or later.
Whether CVE-2026-24056 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
Upgrade pnpm to 10.28.2 or later.
