Latest cPanel update broke phpMyAdmin again. JavaScript error on login, something about Content-Security-Policy and a missing nonce. Not my server, client's. Dell R640, dual Xeon Silver 4214, 128GB RAM. Server's fine. CPanel's not.
Tried three browsers, cleared cache, checked console. Same error. cPanel 124.0.7. Anyone else seeing this? I just want to export a 2GB database without fighting frontend frameworks.

Seen this before with cPanel updates. Specs on my backup box:
PhpMyAdmin is a frontend problem. Use mysqldump, skip the JavaScript entirely.

My test bench showing the error on a 24" monitor 42U rack in background 15A circuit the wife says why do you have a server rack in the living room I say for testing she says testing what I say broken software Power consumption jumped to 380W during cPanel update the wife noticed on the bill
Measured the frustration at 47 retries before giving up and using CLI

Virtualization tax strikes again. CPanel runs on AlmaLinux VM here, 4 vCPU, 8GB allocated. The phpMyAdmin failure isn't kernel-level, but I've seen similar CSP breaks when OpenVZ hosts overcommit and packets fragment weird. Not this case though.
Actual fix: the nonce generation fails if /tmp is mounted noexec on some cPanel builds. Check your mount flags. Idk why I do this at 3am but here's a one-liner anyway
grep noexec /proc/mounts | grep tmp
