An OS command injection vulnerability in alseambusher/crontab-ui through 0.4.2 allows an unauthenticated remote attacker to execute arbitrary system commands by importing a crafted crontab database file. The POST /import endpoint accepts arbitrary .db files and overwrites the application database without validation.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
