CVE-2021-23404Public exploitNetwork attack vector

Database modification via unvalidated cross-origin requests

Published Sep 8, 2021 · Updated Sep 16, 2024

CSRF in the SQL dashboard in Charles Leifer sqlite-web 0.6.5 and earlier allows remote attackers to alter database contents. The drop_column route accepts a cross-origin POST form value and calls the database migrator without verifying a per-request CSRF token or request origin. Exploitation requires a user who can reach the instance to submit an attacker-controlled form, and the resulting request can drop a named database column.
