Affected versions of this package are vulnerable to Missing Authentication for Critical Function via the close_sqleditor_session and check_transaction_status functions in the SQL Editor module, which lack proper authentication checks. An attacker can execute arbitrary code on the server by sending unauthenticated requests to these endpoints, provided they have knowledge of the application's Flask SECRET_KEY and write access to the server's session directory to forge a malicious session file. This is only exploitable if the attacker already possesses the SECRET_KEY and has write access to the sessions directory.
