🔬 Research Details
Description:
async is a utility module which provides straight-forward, powerful functions for working with asynchronous JavaScript.
The function
mapValueswas found to be vulnerable to prototype pollution, when accepting arbitrary source objects from untrusted inputExample of code vulnerable to this issue -
Note that the prototype pollution affects only the prototype of the newly created object (
resultin the example above) and as such is much less destructive than a normal prototype pollutionRemediation:
Development mitigations
Add the
Object.freeze(Object.prototype);directive once at the beginning of your main JS source code file (ex.index.js), preferably after all yourrequiredirectives. This will prevent any changes to the prototype object, thus completely negating prototype pollution attacks.🐸 JFrog Frogbot
