CVE-2026-15432 Observable Timing Discrepancy in Tink-Java and Tink-Android ChunkedMacVerification

When verifying a mac with a ChunkedMacVerification object, Tink compares the resulting tag with non constant time comparison. This potentially allows an attacker to use timinig information as a side channel in order to get information how many bytes of a given tag match the correct tag. This in...

CVE-2026-15432

The CVE concerns Tink-Java and Tink-Android’s ChunkedMacVerification: during tag verification, the implementation uses a non-constant-time comparison, enabling a timing side-channel that could reveal how many bytes of a given tag match the correct tag. This is described as a potential pathway for...

PYSEC-2020-142

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...

GHSA-G5VF-V6WF-7W2R Ciphertext Malleability Issue in Tink Java

Impact Tink's Java version before 1.5 under some circumstances allowed attackers to change the key ID part of the ciphertext, resulting in the attacker creating a second ciphertext that will decrypt to the same plaintext. This can be a problem in particular in the case of encrypting with a...
