⚠️ Watch out! An absolute path traversal vulnerability lurks in the tooxie/shiva-server repository up to version 0.10.0, thanks to an unsafe use of the Flask send_file function. 🕵️♂️ Think of it like a restaurant where the chef gives out the master recipe book without checking who’s asking. Anyone can walk in and whip up any dish, even if they’re not supposed to! An attacker could exploit this vulnerability to access sensitive files on your server, potentially leading to unauthorized data exposure or even system compromise. Imagine a well-guarded vault suddenly offering an open door to anyone with a curious mind — that's the risk!
Think of it like a restaurant where the chef gives out the master recipe book without checking who’s asking. Anyone can walk in and whip up any dish, even if they’re not supposed to! This vulnerability arises because the send_file function in Flask is misconfigured, allowing attackers to use path traversal sequences (like '../') to access files outside of the intended directory.
