The internet is facing a critical threat as a vulnerability in the PHP programming language has the potential to bring down numerous websites. The vulnerability, which has been rated at 9.2 out of 10, is a Remote Code Execution exploit that can allow attackers to run their own code on affected servers. This means that websites and web applications that rely on PHP could be vulnerable to malicious activity, such as data theft and alterations.
According to cybersecurity experts, the impact of this vulnerability could be vast. It is estimated that over 1.3 million internet-connected hosts are likely affected, and since WordPress is used by over 40 percent of the internet, the vulnerability could have a significant impact on the platform. Wordfence, a WordPress security plugin provider, has warned that every WordPress site will be vulnerable because they all run on servers that use PHP.
The European Union Computer Emergency Response Team and the UK National Cyber Security Centre have both issued advisories that encourage companies to isolate their internet-facing apps from public networks or take them offline entirely until the vulnerabilities can be fully mitigated. Mobile operating system developer GrapheneOS has temporarily taken its user discussion forum offline due to proof of concept exploits already being developed.
