Technical details
The editThirdAppConfig handler in JeecgBoot's ThirdAppController lacks authorization checks, allowing any authenticated user to modify third-party integration credentials (client ID, client secret, agent ID, corp ID). The vulnerability requires authentication but permits low-privileged attackers to reconfigure DingTalk, WeCom, or Feishu integrations to attacker-controlled endpoints, enabling credential theft or service disruption.
