Miggo AIRoot Cause Analysis

The vulnerability stems from missing input validation for the 'p2c' parameter during JWE decryption. The commit diff shows:

  1. A new maxPbesCount parameter was added to PbesHmacAesWrapKeyDecryptionAlgorithm constructors
  2. A validation check 'if (pbesCount > maxPbesCount)' was added in getDecryptedContentEncryptionKey
  3. Test cases were added to verify rejection of large p2c values This indicates the vulnerable code path was the decryption processing flow handling the p2c parameter without these limits. The function directly processes untrusted input (p2c header) and lacked resource consumption safeguards before the patch.
