ZDI-CAN-29633 HIGH 7.8 Upcoming Mar 26, 2026

Meta

Meta, the social media and technology company behind Facebook, Instagram, and other platforms, has a local vulnerability with a CVSS score of 7.8 that requires user interaction to exploit but delivers high impact across confidentiality, integrity, and authenticity once activated. The flaw is locally exploitable without authentication, meaning an attacker with physical or local network access can trick a user into triggering the vulnerability to gain unauthorized access to sensitive data or system control. Security teams should monitor for patches between now and the July 24, 2026 deadline and prioritize applying them to systems handling sensitive Meta services or integrated products.
