CVE-2024-21669

Summary

CVE-2024-21669 is a vulnerability affecting Hyperledger Aries Cloud Agent Python (ACA-Py), a foundation for building decentralized identity applications and services. This issue arises when verifying W3C Format Verifiable Credentials using JSON-LD with Linked Data Proofs (LDP-VCs). The flaw lies in the fact that the result of verifying the proof `document.proof` is not properly considered when determining the final `verified` value in the presentation record. As a consequence, holders of such credentials can construct and present incorrect proofs, enabling them to misrepresent their identity. Malicious verifiers can exploit this vulnerability to save and replay presentations from these holders as their own. This issue has been present since version 0.7.0 and was addressed in version 0.10.5.
