Summary

CVE-2025-69264 is a high-severity Protection Mechanism Failure (CWE-693) vulnerability in Pnpm Pnpm. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Abuse Elevation Control Mechanism (T1548); ranked in the top 39% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

CVE-2025-69264 is a vulnerability in pnpm, a JavaScript package manager, affecting versions 10.0.0 through 10.25. It enables git-hosted dependencies to execute arbitrary code during the pnpm install process, bypassing the v10 security feature that disables dependency lifecycle scripts by default. Specifically, while pnpm v10 blocks postinstall scripts via the onlyBuiltDependencies mechanism, git dependencies can still trigger prepare, prepublish, and prepack scripts during the fetch phase, resulting in remote code execution without user consent or approval. The vulnerability is rated 8.8 on the CVSS 3.1 scale (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H) and maps to CWE-693.

A remote attacker can exploit this vulnerability by publishing or controlling a malicious git repository that includes scripts in the prepare, prepublish, or prepack phases. Users running pnpm install on a package that transitively depends on this git-hosted dependency will automatically execute the scripts during the fetch phase, requiring only user initiation of the install command—no additional approval is needed. Exploitation leads to arbitrary code execution on the victim's system, compromising confidentiality, integrity, and availability with high impact.

The vulnerability was published on 2026-01-07 and fixed in pnpm version 10.26.0. Security practitioners should upgrade to 10.26.0 or later. Additional details are available in the GitHub security advisory at https://github.com/pnpm/pnpm/security/advisories/GHSA-379q-355j-w6rj and the fixing commit at https://github.com/pnpm/pnpm/commit/73cc63504d9bc360c43e4b2feb9080677f03c5b5.

finds

Systematic verification that security mechanisms operate according to defined standards reduces the likelihood that protection mechanisms are bypassed or disabled.

mitigates

Hardening devices, disabling vulnerable protocols, and maintaining accurate network diagrams reduce the likelihood that a protection mechanism is misconfigured or left in a weak state.

none

Requiring defined escalation paths, crisis activation criteria, and coordination procedures strengthens the overall protection mechanism so that a single control failure is less likely to leave the organization exposed.

none

By requiring a documented categorization and decision process for security events, the control ensures that protection mechanisms are not bypassed or ignored when anomalies occur.

none

Identifying and remediating control weaknesses that contributed to an incident reduces the likelihood that protection mechanisms will fail again.

none

Post-incident analysis that feeds updated risk assessments and additional controls directly reduces the chance that previously exploited weaknesses will recur.
