CVE-2024-41948 (GCVE-0-2024-41948)
Vulnerability from cvelistv5 – Published: 2024-08-01 22:03 – Updated: 2024-08-07 14:59
VLAI?
Summary
biscuit-java is the java implementation of Biscuit, an authentication and authorization token for microservices architectures. Third-party blocks can be generated without transferring the whole token to the third-party authority. Instead, a ThirdPartyBlock request can be sent, providing only the necessary info to generate a third-party block and to sign it, which includes the public key of the previous block (used in the signature) and the public keys part of the token symbol table (for public key interning in datalog expressions). A third-part block request forged by a malicious user can trick the third-party authority into generating datalog trusting the wrong keypair. This vulnerability is fixed in 4.0.0.

CVE-2022-31053 (GCVE-0-2022-31053)
Vulnerability from cvelistv5 – Published: 2022-06-13 19:35 – Updated: 2025-04-22 17:54
VLAI?
Summary
Biscuit is an authentication and authorization token for microservices architectures. The Biscuit specification version 1 contains a vulnerable algorithm that allows malicious actors to forge valid Γ-signatures. Such an attack would allow an attacker to create a token with any access level. The version 2 of the specification mandates a different algorithm than gamma signatures and as such is not affected by this vulnerability. The Biscuit implementations in Rust, Haskell, Go, Java and Javascript all have published versions following the v2 specification. There are no known workarounds for this issue.
