CVE-2024-21669Public exploitNetwork attack vector

Presentation replay via ignored proof verification

Published Jan 11, 2024 · Updated Jun 3, 2025

Improper proof verification in Aries Cloud Agent Python allows remote authenticated users to accept invalid W3C JSON-LD LDP presentations. The _verify_presentation function considers credential results but omits presentation_result.verified from its final Boolean, so a challenge mismatch still yields verified=true. Reachability requires Linked Data Proof presentation processing; accepted invalid proofs permit presentation replay and impersonation.
