1 high-severity fix in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Command Injection: Using shell=True in subprocess.Popen allows injection of shell metacharacters through untrusted input, leading to arbitrary command execution. The fix removed shell=True, but any future subprocess calls in this or related modules must avoid shell interpretation.
Denial of Service: An ambiguous regex quantifier (*) in the SVN blame parser allowed catastrophic backtracking on crafted blame output, causing CPU exhaustion. The fix changed to + to reduce ambiguity, but similar regex patterns elsewhere may still be vulnerable.
