CVE-2022-31053: Signature forgery in Biscuit

The provided information clearly identifies the vulnerability stems from the use of Γ-signatures in Biscuit v1 specification, but does not provide concrete implementation details or code references to specific functions. While the cryptographic algorithm itself is flawed, the advisory materials:- Do not disclose exact function names/paths- Lack commit diffs or patch details- Describe the vulnerability at specification/algorithm level rather than code level- Show maintainers already removed vulnerable implementations in v2 without documenting specific functionsWithout access to Biscuit v1 source code or implementation details of the Γ-signature aggregation logic, we cannot confidently identify specific vulnerable functions. The vulnerability manifests in the core signature aggregation/verification logic mandated by the v1 spec, but concrete function identification requires code analysis not provided in the advisory materials.
