From bleepingcomputer.com

An exploit has been discovered that could allow ad blocking filter list maintainers for the Adblock Plus, AdBlock, and uBlocker browser extensions to create filters that inject remote scripts into web sites.

With ad blockers having a a user base of over 10 million installs, if malicious scripts were injected it would have a huge impact as they could perform unwanted activity such as stealing cookies, login credentials, causing page redirects, or other unwanted behavior.
