Threat & Defense Details

Likely Mitigating ControlsAI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SI-10 Information Input Validation

addresses: CWE-78 CWE-94

Validates inputs to block special elements that would alter OS command execution.

SC-27 Platform-independent Applications

addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SC-34 Non-modifiable Executable Programs

addresses: CWE-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

SC-44 Detonation Chambers

addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

SI-16 Memory Protection

addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.

Deeper analysisAI

CVE-2025-69262 is a Command Injection vulnerability (CWE-78, CWE-94) in pnpm, a JavaScript package manager. It affects versions 6.25.0 through 10.26.2 and stems from unsafe environment variable substitution in .npmrc configuration files when tokenHelper settings are configured. This flaw allows injected commands during pnpm operations that process these configurations.

An attacker who can control environment variables executed during pnpm operations—such as in CI/CD pipelines or build environments—can exploit the vulnerability to achieve remote code execution (RCE). The CVSS v3.1 base score of 7.5 (AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H) reflects a local attack vector requiring high privileges and complexity, but with potential for high-impact confidentiality, integrity, and availability violations across a changed scope.

The issue is addressed in pnpm version 10.27.0. Security practitioners should upgrade to this version or later. Additional details are available in the pnpm release notes at https://github.com/pnpm/pnpm/releases/tag/v10.27.0 and the GitHub Security Advisory at https://github.com/pnpm/pnpm/security/advisories/GHSA-2phv-j68v-wwqx.
