What is CVE-2026-76846?

Grav prior to version 2.0.16 contains a security flaw due to an incomplete default denylist in the Twig sandbox settings. This oversight allows attackers possessing page-edit permissions to exploit Twig templates using config.get() or config.toArray(), thereby gaining unauthorized access to sensitive system configuration values, such as cache passwords. This vulnerability poses a significant risk, particularly when config_access is enabled, making it critical for users to upgrade to the latest version to mitigate exposure.
