race-conditions

To scan for race condition vulnerabilities, analyze source code to detect time-of-check to time-of-use (TOCTOU) patterns, double-spend issues, and non-atomic operations. The tool supports multiple scanners including semgrep, go vet, and bandit to provide detailed findings with CWE references.

A TOCTOU race condition is a check-then-act vulnerability where shared state changes between validation and execution. It is detected by analyzing source code for time-of-check to time-of-use patterns across asynchronous boundaries without proper locking mechanisms, providing detailed findings with CWE references.

Yes, you can audit shared mutable state across async boundaries. The concurrency analysis detects check-then-act patterns without locking, shared state access issues, and file system race conditions, ensuring thread safety and preventing data corruption or security exploits.

To find double-spend vulnerabilities in payment processing modules, scan for race conditions and incorrect balance updates. The analysis detects non-atomic counter operations and check-then-act patterns without locking, preventing concurrency bugs that could lead to double-spending.

Yes, this concurrency analysis tool works with multiple scanners including semgrep, go vet, and bandit. It leverages these tools to analyze source code for race conditions, thread safety issues, and file system race conditions, providing detailed findings with CWE references.

When scanning for thread safety issues, limitations may include false positives in complex async boundaries and difficulty detecting non-atomic counter operations in dynamically loaded code. The tool focuses on TOCTOU, double-spend, and check-then-act patterns without locking, with detailed CWE references.
