Miggo AIRoot Cause AnalysisThe vulnerability stems from the insecure string comparison in the verify method of Webhook.php. The original code used '==' to compare the received signature with the computed one, which leaks timing information. The fix replaced this with a constant-time comparison via Middleware::stringsEqual, confirming the vulnerability was in the original verify function. The commit diff and CWE-208 (Timing Discrepancy) classification strongly support this conclusion.
