Exposure of Resource to Wrong Sphere in valib
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
valib through 2.0.0 allows Internal Property Tampering. A maliciously crafted JavaScript object can bypass several inspection functions provided by valib. Valib uses a built-in function (hasOwnProperty) from the unsafe user-input to examine an object. It is possible for a crafted payload to overwrite this function to manipulate the inspection results to bypass security checks.
