The application accepts input from an untrusted source (file URL) without proper validation, which can lead to a Server-Side Request Forgery (SSRF) attack. This allows an attacker to make arbitrary requests from the server, potentially leading to unauthorized data disclosure or other malicious activities.
The application uses the EasyOCR library to read text from an uploaded file without proper validation. This can lead to command injection attacks if the input contains malicious commands or script code.
The application downloads files from an untrusted source (file URL) without verifying the integrity of the downloaded file. This can lead to remote code execution vulnerabilities if the file contains malicious content.
The application does not properly handle exceptions, which can lead to information disclosure or denial of service. The generic error message 'error' is returned in case of an exception, providing little insight into the nature of the failure.
