description

JeecgBoot 3.9.5 and earlier contain a server-side request forgery issue in the /openapi/call handler. A remote attacker without authentication may cause the server to make requests; the affected endpoint must be reachable to the attacker.

mitigation

Restrict or block untrusted access to /openapi/call, such as at a reverse proxy or network boundary. Upgrade to a vendor release newer than 3.9.5 after confirming it contains a fix; the evidence does not name a fixed version.

available

yes
automationDeterministic: a check that runs on its own, the same request on every target. Contextual: an agentic technique that needs to be applied per target, for bugs that depend on contextual flows.
