CVE-2026-50014
Description
A flaw was found in pnpm, a package manager. An attacker could exploit this vulnerability by providing a malicious lockfile, which could lead to arbitrary code execution. This occurs because pnpm incorrectly processes git dependency information, allowing a crafted input to execute unauthorized commands during the fetching of git dependencies, particularly for SSH and local transports.
Statement
This Moderate severity flaw in pnpm allows for arbitrary code execution. The vulnerability arises from pnpm's improper handling of git dependency commit values from a malicious lockfile, specifically when using SSH or local git transports. Red Hat products utilizing pnpm, such as Konflux, Red Hat Build of Keycloak, Enterprise Application Platform, and Red Hat AMQ, are affected if they process untrusted pnpm-lock.yaml files with SSH or local git dependencies.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
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.
