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 是一个包管理器。在 10.34.5 之前以及 11.0.0 到 11.11.0 之间，pnpm 使用 从攻击者可控制的 中的包键名解析包名，并在 和 中未经验证地使用了该包名。该包名随后被传递到 、 以及 。当用户运行 时，这允许将包内容写入 目录之外。如果 或匹配的 条目允许执行生命周期脚本，那么逃逸出的包就可以以用户权限执行代码。该问题已在版本 10.34.5 和 11.11.0 中修复。

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.
