The bbPress development team has released bbPress 2.5.13. This release fixes a few bugs, most notably, it readds sanitization to anonymous user data that was accidentally removed in previous versions.
Those who allow anonymous users to create topics and replies on their forums are encouraged to update immediately.
“This feature is not widely used on public forums because spammers aggressively target these kinds of sites, but for communities that rely on this feature, please know you can safely upgrade to 2.5.13 without any issues,” John James Jacoby, lead developer of bbPress and BuddyPress, said.
As a reminder, beginning with bbPress 2.5.12, the minimum version of WordPress supported is 4.7. If you’re using an older version of WordPress, Jacoby recommends using or staying with bbPress 2.5.11.
bbPress 2.6 is still in the release candidate phase as developers iron out a few issues discovered on WordPress.org.
