TLS dan transport for PHP
high5 checks
TLS protects credentials and session cookies in transit. A valid chain, a modern protocol and no downgrade path are the baseline.
What PHP must have
- Certificate chain validates against public trust stores
- Expiry monitored automatically, no manual renewal
- TLS 1.2 and 1.3 only; 1.0 and 1.1 disabled
- HTTP redirects to HTTPS with a permanent redirect
- No mixed content on any page
How to fix it
- 1Enable auto-renewal with your host or CDN and alert at 21 days remaining
- 2Force HTTPS at the edge and remove any route that serves plain HTTP
PHP context
Server-side scripting runtime used by most CMS and many custom apps.
Runtime CVEs are pre-auth and application-independent (PHP2Shell CVE-2026-109618/109619). Keep PHP on a supported, patched branch.
