⚠️ A sneaky RangeError can lead to Arbitrary Code Execution in the safer-eval npm package! That's like a recipe saying, "Just add whatever you want!" without any checks. 😱 Think of the safer-eval package as a kitchen where chefs can create any dish they desire. However, if the kitchen allows any ingredient without checking its source, you could end up with something unsavory — or worse! An attacker could exploit this vulnerability to execute their malicious code, potentially manipulating the application in harmful ways. This could lead to unauthorized access to sensitive information or even a full system compromise, making it essential to address this flaw swiftly.
