Authenticated script execution via crafted job metadata

Published Sep 12, 2026 · Updated Sep 12, 2026

Cross-site scripting in XXL-JOB 3.0 through 3.5.0 allows remote authenticated users to execute script through crafted job metadata. The public record identifies name and author at /jobinfo/insert but does not disclose the exact missing neutralization or output-encoding operation. A valid console session is required to create the job, and a later viewer can have script run in the security context of the scheduling site.
