The PHP Group has warned that this could lead to severe data breaches, including access to sensitive information such as passwords and API keys. As a precaution, several organizations, including government agencies and popular websites, have taken their services offline until the vulnerabilities can be addressed. This incident highlights how AI can exacerbate existing security flaws, making it easier for hackers to exploit them. The widespread reliance on PHP poses a critical risk to internet security, revealing the need for vigilance among web developers and users alike.
