WordPress 4.9.1 security and maintenance release is now available for download. Since its release on November 15, WordPress 4.9 has been downloaded over 6 million times already.
WordPress 4.9 and earlier versions are affected by four security issues which could be exploited as part of a multi-vector attack:
- Use a properly generated hash for the newbloguser key instead of a determinate substring.
- Add escaping to the language attributes used in html
- Ensure the attributes of enclosures are correctly escaped in RSS and Atom feeds.
Eleven other bugs were fixed in WordPress 4.9.1 including some of the issues below:
- Issues relating to the caching of theme template files.
- The inability to edit theme and plugin files on Windows-based servers.
