A critical vulnerability in PHP, the programming language that underpins a large share of the web, has forced websites around the world offline, News.com.au reports. The outage has affected "millions of websites," according to the outlet, and Australian government sites are among those exposed to the flaw, ABC News reports.
OpenAI has framed the episode as a coordinated global response, publishing material under the heading "Patch the Planet" about agents uncovering critical vulnerabilities. The available reporting does not specify the technical nature of the flaw, the exact number of sites taken down, or which government services were disrupted.
The incident points to the concentration of risk in widely used open-source components: a single defect in a language relied on by many platforms can ripple across a large portion of the internet at once. It also highlights the growing role of AI tools in finding security holes, a development that cuts both ways for defenders racing to patch before attackers exploit them.
What to watch next: whether patches are rolled out across affected systems and how quickly exposed government sites return to service.
