| Doc Text: |
A flaw was found in pnpm, a package manager. A remote attacker can exploit a path traversal vulnerability by crafting malicious npm packages. This vulnerability allows the attacker to bypass validation by using bin names starting with an "@" symbol, enabling them to create executable shims or symbolic links (symlinks) outside of the designated `node_modules/.bin` directory. This could lead to arbitrary code execution or privilege escalation on the affected system.
