CVE-2026-42610: Grav Vulnerable to Sensitive Information Disclosure via Accounts Service Bypass

May 5, 2026 (updated May 13, 2026)

Information disclosure exists in Grav CMS v1.8.0-beta.29. Despite previous security patches (notably in v1.8.0-beta.27/28) aimed at restricting sensitive object access within the Twig environment, the Accounts Service remains exposed.

A low-privileged user (EX: Content Editor with only pages.update permissions) can bypass the existing Twig sandbox restrictions by utilizing the grav['accounts'] service. Attacker can programmatically load administrative user objects and extract sensitive data, including Bcrypt password hashes and the security salt.
