Highlights
This release resolves one critical severity vulnerability (CVE-2026-87902) that does not require authentication to exploit. Under certain server and theme conditions, an unauthenticated attacker can cause page template resolution to include a chosen readable local PHP file outside the active theme directories, which could potentially lead to remote code execution.
For full details, see the WordPress 7.1.2 release notes and WordPress documentation.
