Impact
Vulnerability in SecureProps involves a regex failing to detect tags during decryption of encrypted data.
This occurs when the encrypted data has been encoded with NullEncoder and passed to TagAwareCipher, and contains special characters such as \n. As a result, the decryption process is skipped since the tags are not detected. This causes the encrypted data to be returned in plain format.
The vulnerability affects users who implement TagAwareCipher with any base cipher that has NullEncoder (not default).
Patches
The patch for the issue has been released. Users are advised to update to version 1.2.2.
Workarounds
The main recommendation is to update to the latest version as there are no breaking changes.
If that's not possible, you can use 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.

The vulnerability can be exploited over the network without needing physical access. It is difficult for an attacker to exploit this vulnerability and may require special conditions. An attacker needs basic access or low-level privileges. The attacker needs the user to perform some action, like clicking a link. The impact is confined to the system where the vulnerability exists. There is a low impact on the confidentiality of the information.
Limited exploitation activity has been observed. Close monitoring and planned remediation are recommended.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
