Justification

Vulnerable code not in execute path

Impact

Keycloak and Quarkus do not use the async JSON parser from Vert.x which is the vulnerable code path in jackson-core. Confirmed by Quarkus developer @cescoffier and keycloak maintainers in https://github.com/keycloak/keycloak/issues/46757 (closed 2026-03-03). The GHSA specifically describes a vulnerability in the async parser (JsonParserImpl) which is not exercised by keycloak's use of jackson-core.
