CVE-2022-31053 describes a critical vulnerability in Biscuit specification version 1, affecting various Biscuit implementations in Rust, Haskell, Go, and Java. This flaw allows attackers to forge valid Γ-signatures, enabling them to create tokens with arbitrary access levels. With a CVSS score of 9.8 (CRITICAL), this vulnerability is remotely exploitable with low attack complexity, leading to complete compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been observed, the vulnerability's severity necessitates immediate patching to version 2 of the Biscuit specification, which uses a different, unaffected algorithm.
