Kerentanan Improper Handling of Unicode Encoding pada google tink java. Skor CVSS 3.1 5.3 (Medium) menurut NVD.

Deskripsi (NVD)

A mis-handling of invalid unicode characters in the Java implementation of Tink versions prior to 1.5 allows an attacker to change the ID part of a ciphertext, which result in the creation of a second ciphertext that can decrypt to the same plaintext. This can be a problem with encrypting deterministic AEAD with a single key, and rely on a unique ciphertext-per-plaintext.
