⚠️ A tiny flaw in the Delor4/CarceresBE repository opens the door to absolute path traversal due to a careless use of the Flask send_file function! Think of it like a delivery service that delivers parcels to any address a customer claims, even if it’s a restricted zone — all it takes is a wrong instruction and sensitive files could be exposed! 📦 An attacker could exploit this vulnerability to access sensitive files outside the intended directory, potentially leaking confidential data or configuration files. While not confirmed to be exploited yet, the risk is real and could lead to unexpected data exposure!
Think of it like a delivery service that delivers parcels to any address a customer claims, even if it’s a restricted zone — all it takes is a wrong instruction and sensitive files could be exposed! 📦 This vulnerability arises from the Flask send_file function being used without proper checks, allowing attackers to specify absolute paths and access files beyond the application's designated directory.
An attacker could exploit this vulnerability to access sensitive files outside the intended directory, potentially leaking confidential data or configuration files. While not confirmed to be exploited yet, the risk is real and could lead to unexpected data exposure! To mitigate this, ensure that your application properly validates and sanitizes any file paths passed to the send_file function. Also, consider updating to a safe version and implementing strict directory permissions to reduce exposure. You've got this! With these steps, you can secure your application and keep it safe from prying eyes. 🛡️
