+## How to Fix the CVE-2025-8875.json (KeyError: 'opencve') Bug
+
+This issue occurred because CISA added a new entry to its KEV list before MITRE had added it to the official CVE database. An issue has been raised [here](https://github.com/CVEProject/cvelistV5/issues/107).
+
+Because this behavior was undocumented, OpenCVE’s scheduler failed to parse the entry, resulting in the following error:
+
+![Troubleshooting KeyError OpenCVE](images/troubleshooting/key-error-opencve.png){.center style="width:100%"}
+
+The problem has been fixed in this [pull request](https://github.com/opencve/opencve/pull/604).
+
+You can upgrade OpenCVE and relaunch the failed DAG run in your Airflow scheduler instance. To do so, select it:
