An attacker could exploit this vulnerability by crafting a directory path outside of the expected file location. A successful exploit could allow the attacker to create or replace any file on the underlying operating system.","dates":{"published":"2026-03-04T17:39:46.973Z","modified":"2026-03-04T20:50:59.298Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.9,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.9,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.9,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00446,"percentile":0.37745,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.026000000000000068,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.0042},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00446,"percentile":0.37745}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0042,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00437,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00437
