Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Command Injection: Direct inline shell expansion of untrusted workflow step outputs (like version strings) allows adversaries to execute arbitrary shell commands inside the CI runner environment. Mitigation requires passing variables through environment contexts.
Path Traversal: Parsing PEP 723 metadata can allow script dependencies or references to resolve paths outside the project root. Enforcing strict canonicalization and prefix checks ensures that arbitrary file reading does not occur during environment preparation.
