CVE-2026-8233

Researchers Report 84 Flaws in 4G and 5G Cores, Including a Session Hijacking Flaw

Researchers have identified a significant class of 84 previously unknown vulnerabilities, dubbed 'iTrue' flaws, affecting the core networks of 4G and 5G mobile systems. These vulnerabilities stem from implicit trust errors between network functions, exacerbated by the shift to cloud-native deployments. Exploitation could lead to denial-of-service attacks and session hijacking, where an attacker seizes control of a user's network session.
