South Korea's National Security Office convened an emergency cybersecurity meeting in response to a vulnerability affecting PHP, the widely used server-side scripting language. The session was held at the Presidential Office on October 22. The urgency of the gathering underscores the critical role PHP plays in web infrastructure, with millions of sites and services dependent on it. A security flaw at this level can expose vast numbers of systems to exploitation, prompting governments worldwide to treat such disclosures as national security matters. South Korea's swift escalation to its top security body signals heightened concern over potential downstream impacts on digital infrastructure and data integrity.
