jodit is vulnerable to Prototype Pollution
50
Medium Risk
This Affects:
joditTL;DR
Prototype pollution was possible via Jodit.modules.Helpers.set(chain, value, obj) because dot-chains like __proto__.polluted could traverse unsafe keys and mutate Object.prototype (CWE-1321). Version 4.12.26 fixes this by rejecting/bailing out when any chain segment is __proto__, constructor, or prototype, and adds tests to ensure Object.prototype remains unpolluted.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
