Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
xxl-job-admin versions before 3.4.0 are affected by a resource injection flaw in the execution log handling, where the logId argument is improperly controlled. An attacker with remote access can exploit it, though the source describes the attack as highly complex and difficult to exploit, and a public exploit exists. Upgrade xxl-job-admin to version 3.4.0 or later.
