Description

This security bulletin contains information about 2 vulnerabilities.

1) Download of code without integrity check (CVE-ID: CVE-2025-69263)

CWE-ID: CWE-494 - Download of Code Without Integrity Check

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to download of code without integrity check in the tarball resolver when processing HTTP tarball and git-hosted tarball dependencies during installation. A remote attacker can publish a package with a crafted HTTP or git tarball dependency to execute arbitrary code.

User interaction is required to install a package that has an HTTP or git tarball in its dependency tree.

CWE-ID: CWE-693 - Protection Mechanism Failure

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to protection mechanism failure in git dependency lifecycle script handling when processing git-hosted dependencies during pnpm install. A remote attacker can supply a specially crafted git-hosted dependency to execute arbitrary code.

User interaction is required to run pnpm install on a project that includes the malicious dependency.
