CVE-2024-21669: Hyperledger Aries Cloud Agent

High severity, CVSS 8.8. EPSS: 0.6% chance of exploitation in the next 30 days.

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 Cloud Agent: from 0.7.0, before 0.10.5 (fixed in 0.10.5); version 0.11.0 only
