Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: The HTTP instrumentation hooks are highly vulnerable to crashing the host application due to missing null/empty checks on fuzzing headers prior to executing cryptographic functions. Additionally, unbounded memory consumption from HTTP request body chunks can lead to system-wide resource exhaustion.
Path Traversal: Unsanitized URL-encoded file paths allow attackers to bypass path validation mechanisms and manipulate arbitrary local files via write operations.
Denial of Service: Instrumenting database callbacks without verifying if they are already wrapped leads to infinite recursion, triggering stack overflows and causing the parent application to hang or crash.
