Government websites go dark after AI-discovered flaw sparks security scramble

Security agencies warned the flaws could let attackers run code on vulnerable servers without logging in, and some operators took sites offline.

  • On Wednesday, October 21, 2026, PHP developers released emergency security updates addressing two critical remote-code-execution vulnerabilities, CVE-2026-109618 and CVE-2026-109619, urging administrators to apply fixes immediately.
  • Leaked vulnerability details forced the PHP security team to accelerate the release by one day after researchers reported proof-of-concept exploits circulating before official fixes were available.
  • Rated 9.2 on the CVSS v4.0 severity scale, the flaws allow unauthenticated remote code execution, enabling attackers to run malicious code on vulnerable servers without credentials.
  • Government agencies in the Netherlands and Finland took public-facing websites offline as a precautionary measure, following cybersecurity officials' guidance that unpatched systems face severe intrusion risks.
  • Administrators must install patches manually, as automatic platform updates do not apply the fix; older, unsupported PHP versions require specific remediation to ensure system integrity.
