Miggo AIMiggo AIMiggo AIRoot Cause AnalysisThe vulnerability stemmed from the use of providedSignature.contentEquals(signature) in the validation logic. This method performs a short-circuiting comparison, leaking timing information about how many characters matched. The fix replaced it with MessageDigest.isEqual, a constant-time comparison. The commit diff, CVE description, and GitHub issue #12 all explicitly identify this line as the root cause.
