XXL-JOB through 3.5.0-SNAPSHOT is vulnerable to stored cross-site scripting (XSS) in the GLUE code editor. JobCodeController.save() stores the user-supplied glueSource parameter without output encoding, and the FreeMarker template job.code.ftl renders the stored value unescaped.

XXL-JOB <=3.5.0-SNAPSHOT contains a stored Cross-Site Scripting (XSS) vulnerability in the job log list page (/joblog). An authenticated user who holds permission on a target executor job group can inject arbitrary JavaScript via the executorParam argument of the manual-trigger endpoint POST /jobinfo/trigger.

XXL-JOB 3.5.0-SNAPSHOT and earlier contains a Cross-Site Request Forgery (CSRF) vulnerability in the user management controller (JobUserController). The endpoints /user/insert, /user/update, and /user/delete lack CSRF protection and do not restrict HTTP method.

A Server-Side Request Forgery (SSRF) in the xxl-job-admin/jobinfo/trigger component of xxl-job v3.4.0 allows authenticated attackers to scan resources via supplying a crafted HTTP request.

XXL-Job version 2.4.2 contains an insecure direct object reference vulnerability that allows authenticated users to read execution log content from job groups they are not authorized to access by supplying arbitrary sequential log IDs to the logDetailCat endpoint. Attackers can enumerate log records across all job groups by calling the logDetailCat endpoint with incremented logId parameter values, bypassing the permission check present in the sibling logDetailPage endpoint, and retrieve sensitive log content from restricted job groups.

A lateral privilege escalation vulnerability in XXL-Job v2.4.1 allows users to execute arbitrary commands on another user's account via a crafted POST request to the component /jobinfo/.
