    CVE-2026-15432 (GCVE-0-2026-15432)

    Vulnerability from nvd – Published: 2026-07-21 16:42 – Updated: 2026-07-22 18:27
    VLAI
    Title
    Observable Timing Discrepancy in Tink-Java and Tink-Android ChunkedMacVerification
    Summary
    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 turn could allow to find a correct tag bytewise.

    CVE-2020-8929 (GCVE-0-2020-8929)

    Vulnerability from nvd – Published: 2020-10-19 12:15 – Updated: 2024-08-04 10:12
    VLAI
    Title
    Ciphertext integrity weakness in Tink
    Summary
    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.

    Title
    Observable Timing Discrepancy in Tink-Java and Tink-Android ChunkedMacVerification
    Summary
    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 turn could allow to find a correct tag bytewise.

    Title
    Ciphertext integrity weakness in Tink
    Summary
    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.
