⚠️ A sneaky file access issue lurks in the TwentyTwenty.Storage library! This Path Traversal vulnerability lets users reach files outside the designated area, like a toddler finding a hidden stash of cookies. 🍪 Think of it as a delivery driver who ignores the 'no entry' signs and opens all the back doors to the warehouse — if they don’t check what’s inside, they could let all sorts of unwanted surprises in! An attacker could potentially read sensitive files or write unknown data, leading to data breaches or application malfunctions. If your application is using this library without proper input sanitization, it’s like leaving the back door wide open!
Think of it as a delivery driver who ignores the 'no entry' signs and opens all the back doors to the warehouse — if they don’t check what’s inside, they could let all sorts of unwanted surprises in! This Path Traversal vulnerability in the LocalStorageProvider of the TwentyTwenty.Storage library allows attackers to bypass the specified basepath restrictions. If filenames supplied by users aren't sanitized, an attacker can access unintended files on the server.
