BuddyPress 2.9.2 is now available. This is a security and maintenance release. We strongly encourage all BuddyPress sites to upgrade as soon as possible.
The 2.9.2 release addresses five security issues:
- A Cross Site Request Forgery (CSRF) vulnerability was fixed in the interface used by admins to perform certain actions related to sitewide notices. Reported by J.D. Grimes.
- Some uses of serialized data were judged to need hardening. Reported by John James Jacoby of the BuddyPress security team.
- An open redirect was fixed on the user edit screens. Reported by Yasin Soliman (ysx).
- An unauthorized information disclosure vulnerability was fixed in an AJAX handler. Reported by J.D. Grimes.
- A Cross Site Scripting (XSS) vulnerability was fixed in the avatar upload interface. Reported by Ronnie Skansing.
These vulnerabilities were reported privately to the BuddyPress team, in accordance with WordPress’s security policies. Our thanks to all reporters for practicing coordinated disclosure.
In addition, 2.9.2 includes a change that improves compatibility with the upcoming WordPress 4.9 release, by removing the call to a newly deprecated hook.
