Prototype Pollution in handlebars
Versions of handlebars
prior to 3.0.8 or 4.5.3 are vulnerable to prototype pollution. It is possible to add or modify properties to the Object prototype through a malicious template. This may allow attackers to crash the application or execute Arbitrary Code in specific conditions.
Upgrade to version 3.0.8, 4.5.3 or later.
