Description
In Async before 2.6.4 and 3.x before 3.2.2, a malicious user can obtain privileges via the mapValues() method, aka lib/internal/iterator.js createObjectIterator prototype pollution. Some WordPress plugins and themes use this dependency though that doesn’t necessarily mean the plugin itself is vulnerable to exploitation.
