Twig: Sandbox `__toString()` policy bypass via `Traversable` in `join` and `replace` filters
CVSS 4.0
7.1High
Official description
Twig is a template language for PHP. Prior to 3.27.0, the sandbox __toString() checks do not fully cover Traversable values passed to join and replace filters or operands evaluated by the in and not in operators, allowing contained Stringable objects to be coerced to strings without consulting the sandbox policy. This issue is fixed in version 3.27.0.
