What it is

🚨 A sneaky path sanitization issue lets an attacker write or overwrite files outside the target directory. Talk about a recipe for chaos! 🔥 It's like a delivery person accidentally dropping packages at the wrong address because the instructions were vague. Instead of reaching the intended recipient, sensitive files could end up anywhere, causing mayhem. An attacker could leverage this flaw to manipulate or replace critical files in unintended locations, potentially leading to data loss, system corruption, or unauthorized access. The stakes are high, and with a CVSS score of 9.1, it’s a vulnerability that demands immediate attention!
