Arbitrary code execution via compiled selector expressions
Published Nov 13, 2024 · Updated Jan 16, 2025
Code injection in Matthew Mueller dom-iterator before 1.0.1 allows remote attackers to execute arbitrary code through a crafted selector expression. Iterator.prototype.compile passes string expressions through props() into a Function constructor, allowing constructor-chain input to run as JavaScript. Exploitation requires a consuming application to pass attacker-controlled selector expressions, and successful code runs in that application context.
