Meta

Meta, the social media and technology company behind Facebook, Instagram, and other platforms, has a high-severity vulnerability (CVSS 7.8) that requires local access and user interaction to exploit, but once triggered, allows an attacker to completely compromise system confidentiality, integrity, and availability. The flaw does not require authentication, making it particularly concerning for multi-user systems. Security teams should monitor for patches from Meta by late July 2026 and prioritize systems running Meta software, especially in shared computing environments where unauthorized local access is possible.
