{"schemaVersion":3,"id":"CVE-2026-63219","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"GeoNetwork is a catalog application to manage spatially referenced resources. Prior to versions 4.4.12 and 4.2.17, the API endpoint for creating a new formatter via file upload is unprotected and allows the upload of external uncontrolled files. An unauthenticated attacker can upload arbitrary `.xsl` or `.zip` formatter files to the server.  An unauthenticated attacker can write arbitrary files into the GeoNetwork formatter directory. On its own this constitutes unauthorized write access to server storage. The issue is patched in GeoNetwork versions 4.4.12 and 4.2.17.","dates":{"published":"2026-09-03T17:13:01.357Z","modified":"2026-09-03T17:40:21.680Z","reserved":null,"kevAdded":["2026-09-02T00:00:00.000Z"],"kevDue":[]},"cvss":{"headline":{"score":8.6,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":8.6,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8.6,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00466,"percentile":0.39009,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00466},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00466,"percentile":0.39009}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00466,"percentile":null},{"date":"2026-10-10
