Critical Vulnerability in NestJS Devtools: Localhost RCE via Sandbox Escape
A flawed sandbox in @nestjs/devtools-integration lets attackers run code on your machine via CSRF, leading to full Remote Code Execution (RCE).
There are plenty of modules for doing recursive filesystem operations. These have slightly different semantics than the ones I saw previously.
This module provides three main functions:
This behaves much like "cp -R", except that only regular files, symlinks, and directories are supported (not pipes or devices). Like "cp", this operation fails if the destination already exists. If any part of the operation fails, the partial copy will still be present.
This implementation will only allow 100 outstanding filesystem operations at a time. If you need more, you can bump cpMaxWorkers, but beware of system resource limits (e.g., file descriptors).
This behaves much like "rm -r". Unlike copyTree, this one does not attempt to limit the number of outstanding filesystem operations, but it also doesn't use a file descriptor per file in the tree.
On illumos systems, this creates a read-only lofs mount of "source" at "dest". This just calls the underlying mount(1M) command.
