I will patch PHP security vulnerabilities
Sergey A
About this gig
Im a full-stack developer with 8+ years of experience, including production server administration (Linux, PHP-FPM, Apache/Nginx, DevOps).
Recent critical PHP vulnerabilities (like CVE-2026-109618 / CVE-2026-109619 PHP2Shell) can let attackers run code on your server with no authentication required. If you're not sure whether your server is exposed, I can help.
What I do:
- Audit your current PHP version, server stack, and exposure to known CVEs
- Safely update PHP to a patched version with zero/minimal downtime
- Apply server-level hardening (disable risky settings, limit request sizes, restrict file upload paths)
- Full backup before any change, with a rollback plan if something breaks
- Post-update compatibility check (site, plugins, custom code, see packages)
- Clear report of what was found and what was fixed
I work with shared hosting (cPanel/Plesk), VPS, and dedicated servers.
Message me with your hosting type and current PHP version before ordering so I can scope the job correctly.
