ÂLIM rebuilt it, wrote a proof of concept, and confirmed it fires on the vulnerable build and stays silent on the patched one.
W3 Total Cache has patched CVE-2026-18051. Every version before 2.10.5 on the default Disk: Enhanced page cache lets an unauthenticated request write a file into any existing directory, inside or outside the web root. No login, no token, no click.
The advisory's ".htaccess overwrite" half does not fire on a stock install. We checked: after a successful write the site .htaccess was byte for byte unchanged.
