JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the editThirdAppConfig handler that allows any authenticated user to modify third-party application configurations. Low-privileged attackers can replace client id, client secret, agent id and corp id of DingTalk, WeCom or Feishu integrations to redirect directory synchronisation and messaging to attacker-controlled applications or break them.
