What’s happening: Two critical security flaws in PHP – the technology behind millions of websites and online applications – have prompted urgent warnings and emergency software updates. The vulnerabilities could allow hackers to take control of affected web servers without login credentials, potentially exposing sensitive business and customer information.
Why it matters: Businesses using vulnerable PHP systems could face data theft, website disruptions or unauthorized changes to their systems. Popular website platforms, including WordPress, may be affected depending on their underlying PHP installations.
What businesses should do now:
- Check your exposure. Ask your IT team, website host or technology vendors whether your systems use affected PHP versions.
- Update immediately. Confirm that available security patches have been installed, prioritizing public-facing websites, customer portals and applications.
- Watch for suspicious activity. Review systems for signs of unauthorized access and ensure cybersecurity response plans are ready.
The bottom line: Cyber threats are evolving – and attackers are increasingly exploiting software vulnerabilities. Verizon’s 2026 research found that roughly 31% of data breaches involved exploitation of these flaws.
- For Michigan businesses, this latest warning underscores the importance of timely security updates, vendor oversight and having a cybersecurity response plan ready.
