Miggo AIMiggo AIMiggo AIRoot Cause AnalysisThe vulnerability stemmed from using regular string comparison (==) in the token validation logic. The commit diff shows the critical fix replaced this with constant_time_eq() in TOTP<T>::check. This function's comparison of generated tokens with user input was vulnerable to timing analysis, as string equality checks in most languages (including Rust) short-circuit on first mismatch. The direct replacement with a constant-time comparison function in the patched version confirms this was the vulnerable point.
