**[WordPress Responds to Critical PHP Vulnerability: Website Operators Urged to Update Immediately]** According to Deep Tide TechFlow, on October 22, WordPress issued a security advisory stating that the PHP project has released a security update. Due to the severity of the vulnerability, website owners are strongly advised to update PHP immediately and contact their hosting providers to confirm the deployment of patches and the implementation of Web Application Firewall (WAF) mitigation rules. Users can check the current PHP version running on their website via the WordPress dashboard under "Tools > Site Health > Info > Server." Versions of PHP prior to 8.2 are no longer receiving official security updates. For websites still running outdated versions and managed on self-hosted servers, if immediate fixes cannot be applied, the official recommendation is to consider temporarily taking the server offline until the vulnerability is effectively mitigated. WordPress emphasized that this vulnerability is not exclusive to its platform but affects servers running PHP applications.
