# CVE-2026-55697

> 7.5 HIGH · 🧪 PoC

## Beschreibung

pnpm is a package manager. Prior to 10.34.2 and 11.5.3, pnpm can install configDependencies declared in pnpm-workspace.yaml before command dispatch. Before the patch, a repository could declare pacquet or @pnpm/pacquet as a config dependency and pnpm treated that repository-controlled dependency as an install-engine opt-in. During install, pnpm resolved a platform-specific @pacquet/-/pacquet binary from node_modules/.pnpm-config/ and spawned it as the developer or CI user. This vulnerability is fixed in 10.34.2 and 11.5.3.
