Description

Hyperledger Aries Cloud Agent Python (ACA-Py) is a foundation for building decentralized identity applications and services running in non-mobile environments. When verifying W3C Format Verifiable Credentials using JSON-LD with Linked Data Proofs (LDP-VCs), the result of verifying the presentation `document.proof` was not factored into the final `verified` value (`true`/`false`) on the presentation record. The flaw enables holders of W3C Format Verifiable Credentials using JSON-LD with Linked Data Proofs (LDPs) to present incorrectly constructed proofs, and allows malicious verifiers to save and replay a presentation from such holders as their own. This vulnerability has been present since version 0.7.0 and fixed in version 0.10.5.

Affected products

hyperledger aries-cloudagent-python: from 0.7.0 before 0.10.5; 0.11.0-rc1, 0.11.0-rc2 — fixed in 0.10.5

How to fix

Upgrade to a fixed version: hyperledger aries-cloudagent-python 0.10.5. Check the vendor advisory for mitigations.
