⚡ An attacker with just the right admin privileges can craft some seriously sneaky credentials in gardenctl versions 2.11.0 and below! 🔥 This is like a mischievous vendor slipping counterfeit coupons into a cash register—if the cashier doesn't check, they could unwittingly accept those fake coupons and lose money while handing out real discounts! If exploited, an attacker could break out of the intended string context in Fish or PowerShell setups, effectively gaining unauthorized access and control over the Gardener project. This could lead to unauthorized operations in your cloud infrastructure, making it a dangerous scenario for any environment relying on these shells.
