Hyperledger Aries Cloud Agent Python result of presentation verification not checked for LDP-VC
The advisory, in context
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.
Patches
This issue has been patched in version 0.10.5 and fixed in 0.11.0.
Workarounds
There is no workaround other upgrading to a patched/fixed version of ACA-Py.
Affected packages
Start with the recorded fix for your release branch. Check your installed version and test compatibility before upgrading. Fixing this advisory does not rule out other vulnerabilities in the release.
