Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Command Injection: The use of shell=True with string-formatted arguments in subprocess.Popen allowed attackers to execute arbitrary system commands via manipulated inputs in the third-party runner integration.
Denial of Service: Algorithmic complexity (ReDoS-like backtracking) in the custom glob matching logic could be exploited to cause extreme CPU consumption and system hangs via specifically crafted metadata filters.
