CVE-2026-7306
Xuxueli xxl-job OpenAPI Endpoint OpenApiController.java hard-coded key
Description

A security vulnerability has been detected in Xuxueli xxl-job up to 3.3.2. The impacted element is an unknown function of the file xxl-job-admin/src/main/java/com/xxl/job/admin/scheduler/openapi/OpenApiController.java of the component OpenAPI Endpoint. Such manipulation of the argument default_token leads to use of hard-coded cryptographic key . It is possible to launch the attack remotely. A high complexity level is associated with this attack. The exploitability is regarded as difficult. The exploit has been disclosed publicly and may be used.
