CVE-2026-46635Network attack vector

Sandbox property disclosure via unchecked column filter

Published Jul 14, 2026 · Updated Jul 14, 2026

Incorrect authorization in Twig before 3.26.0 allows remote authenticated users to read disallowed object properties through sandboxed templates. The column filter passes object arrays to PHP array_column(), which reads public and magic properties without invoking CoreExtension::getAttribute() or SandboxExtension::checkPropertyAllowed(). Exploitation requires an untrusted template author, sandbox mode, the column filter in allowedFilters, and a reachable object; impact is limited to property disclosure.
