Due to the absence of proper file extension checks, MIME type validation, and authentication, attackers can upload executable PHP files to a web-accessible directory (/files/). This allows them to execute arbitrary commands remotely by accessing the uploaded script, resulting in full Remote Code Execution (RCE) without authentication.","dates":{"published":"2025-05-09T00:00:00.000Z","modified":"2025-05-10T01:57:45.325Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":9.8,"severity":"critical","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":9.8,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":9.8,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.01202,"percentile":0.67951,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.11000000000000003,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.01092},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.01202,"percentile":0.67951}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01092,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01202,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01202,"percentile":null},{"date"
