Overview

Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity in that downloaded addon updates are not checked to match the version selected from the manifest for that update. If the manifest had been tampered with on the server, an attacker could trick the browser into downgrading the addon to a prior version.
