Description
A security flaw has been discovered in Xuxueli xxl-job up to 3.3.2. Impacted is the function logDetailCat of the file xxl-job-admin/src/main/java/com/xxl/job/admin/controller/biz/JobLogController.java of the component Execution Log Handler. The manipulation of the argument logId results in improper control of resource identifiers. The attack may be performed from remote. This attack is characterized by high complexity. The exploitability is considered difficult. The exploit has been released to the public and may be used for attacks. Upgrading to version 3.4.0 is recommended to address this issue. The patch is identified as d24e4ccd6073cc75305e1d3b9c29bc8db7437e7a. It is suggested to upgrade the affected component.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.xuxueli:xxl-job-admin. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update com.xuxueli:xxl-job-admin to 3.4.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-7303 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-7303 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-7303. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
