CVE-2026-7306 Details
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.
A vulnerability in Xuxueli XXL-Job versions through 3.3.2 allows unauthenticated access to privileged OpenAPI endpoints. The issue arises because the application ships with a default access token, 'default_token', which is not changed before deployment. This default token is used to authorize access to management operations such as registering executors, removing registrations, and submitting task execution callbacks. The vulnerability can be exploited remotely, but requires a high level of complexity.
Users are advised to change the default access token to a strong, random value before deploying the application. XXL-Job should not be started with the access token set to 'default_token'. Additionally, the OpenAPI management operations should not rely solely on a static shared token for authorization.
