# Patch Next advisory brief: CVE-2026-7303

Advisory: xxl-job has a Resource Injection issue
IDs: CVE-2026-7303, GHSA-gw2x-mfwr-h46p
Record: https://patchnext.com/advisories/cve-2026-7303 (revision 1, source checked 26 Oct 2026, 16:45 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 2.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: com.xuxueli:xxl-job-admin 3.4.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.xuxueli:xxl-job-admin: affected < 3.4.0; fixed in 3.4.0

## Suggested inspection (read-only)
- Maven com.xuxueli:xxl-job-admin: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on com.xuxueli:xxl-job-admin.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-gw2x-mfwr-h46p (GitHub-reviewed advisory GHSA-gw2x-mfwr-h46p lists affected ranges: Maven com.xuxueli:xxl-job-admin >=0 <3.4.0)
