This is due to insufficient limitations on the email recipient and the content in the 'send_pdf' and the 'send_pdf_front' functions which are reachable via AJAX. This makes it possible for unauthenticated attackers to send emails with any content to any recipient.","dates":{"published":"2024-06-19T03:12:28.211Z","modified":"2026-04-08T16:32:53.642Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.8,"severity":"medium","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:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.8,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.8,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"wordfence","score":5.8,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00349,"percentile":0.2723,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00349},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00349,"percentile":0.2723}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00349,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0
