Upgrade ilicmiljan/secure-props to version 1.2.2 or higher.
Overview
Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity due to the TagAwareCipher process. An attacker can cause the decryption process to be skipped, resulting in encrypted data being returned in plain format, by encoding the data with NullEncoder and including special characters such as \n which are not detected by the regex used for tag detection.
Note
This is only exploitable if TagAwareCipher is implemented with any base cipher that has NullEncoder (not default).
Workaround
This vulnerability can be mitigated by using the default Base64Encoder with the base cipher decorated with TagAwareCipher to prevent special characters in the encrypted string from interfering with regex tag detection logic.
This workaround is safe but may involve double encoding since TagAwareCipher uses Base64Encoder by default.
