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:

Quét site miễn phíThe 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.
There is no workaround other upgrading to a patched/fixed version of ACA-Py.
