nuts-node: JWT type confusion in v1 access token introspection allows VP replay as access token
nuts-node is the reference implementation of the Nuts specification. Prior to 6.2.3 and 5.4.31, the v1 access token introspection endpoint (/auth/v1/introspect_access_token) accepts any JWT signed by a key present on the node, without validating the JWT type, issuer-to-key binding, or required claims. This allows a Verifiable Presentation (VP) JWT to be replayed as an access token and receive an active: true introspection response. This vulnerability is fixed in 6.2.3 and 5.4.31.
