pnpm path traversal vulnerability

PNPM is a package manager developed by the open-source project Pnpm. Prior to version 10.28.1, Pnpm had a path traversal vulnerability. This vulnerability stemmed from the tarball extraction process, which allowed for path traversal attacks. As a result, malicious packages could write files outsi...

GHSA-2657-3C98-63JQ esm.sh has a path traversal in extractPackageTarball enables file writes from malicious packages

Summary The commit does not actually fix the path traversal bug. path.Clean basically normalizes a path but does not prevent absolute paths in a malicious tar file. PoC This test file can demonstrate the basic idea pretty easily: go package server import "archive/tar" "bytes" "compress/gzip"...

jaraco.context path traversal vulnerability

jaraco.context is a Python library developed by Jason R. Coombs. Versions 5.2.0 to 6.1.0 of jaraco.context had a path traversal vulnerability. This vulnerability stemmed from the Zip Slip path traversal in the tarball functions, which could allow files to be extracted outside of the expected...
