Why it matters
If PHP or PHP-like files can execute from uploads, a successful file upload vulnerability can become direct code execution.
What Steel Security checks
Steel checks whether uploads execution blocking appears present and whether the current server family supports managed edits.
What Steel Security can do
On Apache and LiteSpeed, Steel manages a scoped `.htaccess` block.
On IIS, Steel manages a scoped `web.config` section.
On Nginx, Steel shows manual guidance instead of pretending it can edit server configuration safely from inside WordPress.
- Managed apply and rollback on Apache/LiteSpeed
- Managed apply and rollback on IIS
- Manual guidance only on Nginx
Rollback / Recovery
Rollback removes only the Steel-managed block or section, rather than rewriting unrelated server configuration.
