Description
CVE-2026-72589 is a critical OS command injection vulnerability in alseambusher's crontab-ui versions prior to 0.4.3. It allows unauthenticated remote attackers to execute arbitrary system commands by importing a crafted crontab database file via the POST /import endpoint, which accepts arbitrary .db files without validation and overwrites the application database.
