BuddyPress 7.2.1 is now available. This is a security release. All BuddyPress installations are strongly encouraged to upgrade as soon as possible.
- A vulnerability was fixed that could allow a privilege escalation from a regular user to Administrator, using the BuddyPress REST API
- A vulnerability was fixed that could allow a member to force a friendship on behalf of another member, using the BuddyPress REST API
- A vulnerability was fixed that could allow a member to read private messages in a thread they were not invited to, using the BuddyPress REST API
- A vulnerability was fixed that could allow a member to invite another member to join a group without being friends when that group restricted invites to friends only, using BuddyPress Nouveau and the BuddyPress REST API
- A vulnerability was fixed that could allow a user that has just been demoted from an Administrator role to a Subscriber to add/edit/delete BuddyPress Member Types from the Administration screens introduced in the 7.0.0 release.
The BuddyPress Team also conducted a comprehensive security audit on all BuddyPress REST API endpoints, which led to:
- Improving all permission methods to use a WP_Error object as the default return value.
- Fixing unintended behavior allowing any member to edit their own Member Type.
- Fixing unintended behavior that allowed any logged in member to list the members of a private group.

Our deepest gratitude goes out to Kien for practicing coordinated disclosure and being extremely patient while we worked through these issues.
