Lifecycle Timeline
1DescriptionCVE.org
A vulnerability was identified in Xuxueli xxl-job up to 3.5.0. This vulnerability affects unknown code of the file /jobinfo/insert. Such manipulation of the argument name/author leads to cross site scripting. The attack can be executed remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Stored cross-site scripting in Xuxueli xxl-job up to version 3.5.0 permits an authenticated low-privileged user to inject malicious script content via the name or author parameters of the /jobinfo/insert endpoint, which is later rendered unsanitized to other users who view the job listing interface. The CVSS 4.0 score of 2.0 reflects the constrained real-world impact: exploitation requires a valid account and passive victim interaction, with impact limited to low integrity effect and no confidentiality or availability consequence. …
