CVE-2026-108883 · Severity: medium · CVSS 6.5 · Published 2026-10-11

JeecgBoot is a low-code development platform used to build enterprise applications. An authenticated user can modify third-party integrations like DingTalk, WeCom, or Feishu by changing credential values in the application configuration, without proper permission checks. An attacker with any user account could redirect directory synchronization or messaging to their own services, potentially intercepting data or disrupting communications.

## 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.
