The POST /import endpoint accepts arbitrary .db files and overwrites the application database without validation. The hook field value is embedded directly into a shell command by crontab.js makeCommand() without sanitization, so a malicious hook value in the imported file results in command execution on the next cron execution cycle.","published":"2026-08-10T11:17:32.003","modified":"2026-08-10T11:17:32.003","cvss":{"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"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/alseambusher/crontab-ui"},{"type":"WEB","url":"https://github.com/alseambusher/crontab-ui/blob/master/crontab.js"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-10T11:17:32.003"}}
