"The version of pnpm installed on the remote host is prior to 10.34.0, or 11.x prior to 11.4.0. It is, therefore,
affected by multiple vulnerabilities:

  - 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 cause pnpm install --ignore-scripts to replace paths in the current
    project with symlinks to attacker-controlled dependency package directories. (CVE-2026-50016)

  - 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 delete arbitrary files on the filesystem during pnpm install, as
    the user running the install. (CVE-2026-50015)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
