CVE-2024-45411Network attack vector

Sandbox bypass via reused unsandboxed template

Published Sep 9, 2024 · Updated Sep 16, 2024

Sandbox bypass in Twig before 1.44.8, 2.16.1, or 3.14.0 allows remote authenticated users to run prohibited template operations. CoreExtension::include renders a previously cached, non-sandboxed named template without calling checkSecurity at runtime. The bypass requires global sandboxing to be disabled, a sandboxed include by template name, and prior loading of that template outside the sandbox.
