Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Insecure handling of ZIP entry names during unpack and extract operations allows arbitrary file write outside the designated directory. This could lead to remote code execution if system files or configuration files are overwritten. The issue was addressed by implementing rigorous path canonicalization and prefix validation.
