CVE-2026-82392— pnpm: Virtual store linker path traversal via unvalidated depPath name in lockfileToDepGraph

Quick assessment

Affected
pnpm pnpm
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

pnpm是pnpm团队开源的一款高效的JavaScript包管理器。 pnpm 10.34.5之前版本和11.0.0至11.11.0之前版本存在路径遍历漏洞，该漏洞源于解析攻击者控制的pnpm-lock.yaml包名后未进行验证，导致包内容可被写入node_modules目录之外，当允许生命周期脚本时，可能以用户权限执行代码。

Vulnerability Title
pnpm: Virtual store linker path traversal via unvalidated depPath name in lockfileToDepGraph
Source: CVE Program / CVE List V5
Vulnerability Description
pnpm is a package manager. Prior to 10.34.5 and from 11.0.0 until 11.11.0, pnpm parses the package name from attacker-controlled pnpm-lock.yaml packages keys with dp.parse(depPath).name and uses it without validation in deps/graph-builder/src/lockfileToDepGraph.ts and pnpm11/deps/graph-builder/src/lockfileToDepGraph.ts. The name reaches path.join(modules, pkgName), storeController.importPackage, and pnpm11/lockfile/to-pnp/src/index.ts, allowing package contents to be written outside node_modules when a user runs pnpm install. When dangerouslyAllowAllBuilds or a matching allowBuilds entry permits lifecycle scripts, the escaped package can execute code with the user's privileges. This issue is fixed in versions 10.34.5 and 11.11.0.
