What is CVE-2026-11502?

A vulnerability exists in JeecgBoot versions up to 3.9.2 due to a flaw in the Third-Party Login functionality. This weakness allows an attacker to manipulate the state argument in the HttpServletResponse.sendRedirect method, resulting in an open redirect. Although the attack requires a degree of complexity and social engineering tactics to induce user interaction with a malicious OAuth link, the potential for exploitation remains concerning. Notably, the third-party login feature is optional and often disabled in many deployments, reducing the overall risk in practical scenarios.
