CVE-2026-52371Public exploitNetwork attack vector

Internal resource access via unchecked address override

Published Jul 31, 2026 · Updated Jul 31, 2026

SSRF in xxl-job 3.4.0 jobinfo/trigger allows remote authenticated users to reach HTTP resources from the admin server. The addressList parameter overrides the job group's configured executor address without verifying that the supplied URL belongs to a trusted executor. A user with access to one job group can induce POST /run requests to internal services and disclose the platform access token and job metadata to a controlled endpoint.
