Korea raises cyber alert over critical PHP flaws
South Korea's science ministry raised the private-sector cyber crisis alert from 'interest' to 'caution' at noon on Oct. 22 after two critical vulnerabilities were found in PHP, a language used by about 70-75% of websites worldwide, Yonhap and Dong-A Ilbo report. The ministry and KISA have urged companies and agencies running websites to check PHP use and apply updates, with emergency patch support under review, according to Chosun Ilbo and KBS World. The flaws, rated 'emergency' in severity, could let attackers take over systems without authentication, KBS World notes. KISA identified the issues on Oct. 21 as CVE-2026-109618 (improper handling of exceptional conditions) and a use-after-free bug, Dong-A Ilbo adds. Japan's prime minister has also urged immediate patching, with Japanese government and firms responding, Kyunghyang Shinmun reports.
