CVE-2026-46639Network attack vector

Sandbox data exposure via disabled attribute policy checks

Published Jul 14, 2026 · Updated Jul 14, 2026

Protection mechanism failure in Twig 3.24.0 through 3.25.0 allows remote authenticated users to access restricted object attributes. ObjectDestructuringSetBinary::compile() hardcodes the sandbox argument to false when emitting CoreExtension::getAttribute(), bypassing SecurityPolicy property and method checks. Exploitation requires write access to a sandboxed template and the do tag to be allowed; exposed objects can reveal public properties or execute public getters.
