CVE-2025-69262
Description
A flaw was found in pnpm. This command injection vulnerability allows an attacker who can control environment variables during pnpm operations to execute arbitrary code. The vulnerability arises from improper handling of environment variable substitution within .npmrc configuration files, particularly when tokenHelper settings are used. Successful exploitation can lead to remote code execution in build environments.
Statement
This vulnerability is rated Moderate for Red Hat. The flaw in pnpm allows for remote code execution via command injection when environment variable substitution is used in .npmrc files with tokenHelper settings. Exploitation requires an attacker to control environment variables and place malicious scripts, primarily impacting build environments such as CI/CD pipelines or Docker builds. Red Hat products like Enterprise Application Platform are not directly affected by this pnpm vulnerability.
Mitigation
To reduce exposure, avoid using the tokenHelper setting in .npmrc configuration files. Instead, configure authentication using direct tokens. It is also recommended to audit and restrict environment variables in build environments, including CI/CD pipelines and container build processes, to prevent unauthorized control.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Confidentiality,Integrity,Availability,Non-Repudiation
Technical Impact: Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart; Read Files or Directories; Modify Files or Directories; Read Application Data; Modify Application Data; Hide Activities
Attackers could execute unauthorized operating system commands, which could then be used to disable the product, or read and modify data for which the attacker does not have permissions to access directly. Since the targeted application is directly executing the commands instead of the attacker, any malicious activities may appear to come from the application or the application's owner.
