Many older versions of ZIP crates and packages are vulnerable to these discrepancies. Keeping your dependencies current is the first line of defense.

An attacker can hide a "path traversal" payload (like ../../tmp/malware ) that only the Extractor sees, effectively slipping it past the security check. Why It’s a Problem for Developers File: Schizophrenia.zip ...
