What it is

🚨 A single, unvalidated path in LG Simple Editor lets attackers delete any file they want! ⚡ Think of it like a restaurant that lets anyone in to toss out any dish they dislike — without checking who they are or what they’re doing. That’s the kind of chaos a malicious user can unleash here! An attacker could swiftly delete critical files from your server, potentially crippling operations or erasing important data. Imagine coming into work and discovering that crucial documents or configurations have vanished into thin air! This vulnerability poses a serious risk, especially since no authentication is needed to exploit it.
