CVE-2024-51755Network attack vector

Sandbox escape via unchecked ArrayAccess attributes

Published Nov 6, 2024 · Updated Nov 7, 2024

Sandbox escape in Twig before 3.11.2 and 3.12.0 through 3.14.0 allows remote authenticated users to read restricted object attributes. CoreExtension::getAttribute resolves ArrayAccess offsets and invokes __isset() before the sandbox policy calls checkPropertyAllowed on the requested attribute. Exploitation requires sandbox mode, a user-controlled template expression, and an application-provided ArrayAccess object; the demonstrated consequence is restricted-data disclosure.
