Updated: the lock installs core v5.1.0, whose file and image storage runs on Flysystem 3. league/flysystem moves from 2.x to 3.x (and league/flysystem-memory to 3.x; league/flysystem-local is added). This fixes CVE-2026-102601 / GHSA-cxf4-7mrp-vvpr, a bypass of the path normalizer's control-character check used for uploaded file names, the advisory v5.0.3.3 listed as known. composer audit reports no advisories.

No configuration change is needed in projects.

Verified before tagging with a fresh install from Packagist (installed from the lock), the documented SQLite steps and PHP's built-in server without a router: 17/17 page and sign-in checks, legacy rich text publish, the admin 404s and the Exponential footer, and 17/17 storage checks — image upload, the original and a resized variation served and on disk, binary file download byte for byte, and both files removed from disk on delete. No CRITICAL in the Platform log, no legacy error log.
