"The version of pnpm installed on the remote host is prior to 10.34.2, or 11.x prior to 11.5.3. It is, therefore,
affected by multiple vulnerabilities:

  - pnpm and pacquet expanded ${ENV_VAR} 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 environment secrets to an attacker-selected registry
    before lifecycle scripts run. (CVE-2026-55180)

  - 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 normalized to the same value. (CVE-2026-55487)

  - pnpm can install configDependencies declared in pnpm-workspace.yaml before command dispatch. A
    repository could declare pacquet or @pnpm/pacquet as a config dependency and pnpm treated that
    repository-controlled dependency as an install-engine opt-in, allowing execution of arbitrary binaries.
    (CVE-2026-55697)

  - pnpm can persist package-manager bootstrap metadata in pnpm-lock.yaml. A malicious repository could
    commit package-manager lockfile package records and snapshots that bypassed fresh package-manager
    resolution, then cause pnpm to install and execute bytes selected by that committed lockfile state.
    (CVE-2026-55698)

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