Name of the Vulnerable Software and Affected Versions biscuit-rust (affected versions not specified)

Description The issue concerns biscuit-rust, the Rust implementation of Biscuit, an authentication and authorization token for microservices architectures. A third-party block request forged by a malicious user can trick the third-party authority into generating datalog trusting the wrong keypair. This occurs because third-party blocks can be generated without transferring the whole token to the third-party authority, using a ThirdPartyBlock request that includes the public key of the previous block and the public keys part of the token symbol table.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
