+Version 4.7.2

+Release Date: March 24, 2026

+**********
+Bugs Fixed
+**********
+
+- **Security:** Fixed a bug where the CSRF filter could corrupt JSON request bodies after successful
+    verification when the CSRF token was provided via the ``X-CSRF-TOKEN`` header.
+    This caused ``IncomingRequest::getJSON()`` to fail on valid ``application/json`` requests.
+
+See the repo's
+`CHANGELOG.md <https://github.com/codeigniter4/CodeIgniter4/blob/develop/CHANGELOG.md>`_
+for a complete list of bugs fixed.
