What happened

### Impact

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. Below is an example result from verifying a JSON-LD Presentation where there is an error noted in the processing (mismatched challenge), but the overall result is incorrectly `"verified": true`:

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 the first implementation of support for JSON-LD W3C Verifiable Credential Data Model presentations, in Aries Cloud Agent Python release in 0.7.0.

All ACA-Py Users depending on W3C Format Verifiable Credentials using JSON-LD with Linked Data Proofs are impacted by this vulnerability.

Evidence summary (plain text)

Hyperledger Aries Cloud Agent Python result of presentation verification not checked for LDP-VC (Jan 9, 2024).
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. Below is an example result from verifying a JSON-LD Presentation where there is an error noted in the processing (mismatched challenge), but the overall result is incorrectly `"verified": true`:
