Описание
pnpm is a package manager. From 11.3.0 until 11.5.3, pnpm stage download derived a local filename from registry-controlled package name and version fields. A crafted manifest could escape the selected download directory and overwrite another reachable file. The merged fix validates both fields, derives one safe filename, and verifies the final destination before writing. This vulnerability is fixed in 11.5.3.
A flaw was found in pnpm, a package manager. A remote attacker could exploit a vulnerability in the pnpm stage download command by providing a specially crafted package manifest. This could allow the attacker to write files to arbitrary locations on the system, leading to unauthorized modification of system files and potential integrity compromise.
Отчет
This Important flaw in pnpm allows a remote attacker to achieve arbitrary file write by providing a specially crafted package manifest during the pnpm stage download operation. This could lead to unauthorized modification of system files and compromise system integrity, particularly in environments where pnpm processes untrusted package sources.
