CVE-2026-7303 — Xuxueli xxl-job Execution Log JobLogController.java logDetailCat resource injection

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.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.7% (30-day exploitation probability)+8
  • CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Xuxueli Xxl-job).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  4. Search available logs for exploit probes, errors and authentication anomalies.
