CVE-2026-16367

A critical vulnerability in Firefox allows for a sandbox escape through an invalid pointer in the Disability Access APIs component, potentially enabling attackers to execute arbitrary code outside of the browser's security confines. Users and organizations relying on Firefox for secure web browsing should prioritize updating to version 153 or later to mitigate this severe risk. This issue poses a significant threat to any environment where Firefox is deployed, particularly in sensitive or high-security contexts.
