CVE-2024-51754
LOW2.2EPSS 0.14%Twig has unguarded calls to `__toString()` when nesting an object into an array
描述
### Description In a sandbox, an attacker can call `__toString()` on an object even if the `__toString()` method is not allowed by the security policy when the object is part of an array or an argument list (arguments to a function or a filter for instance). ### Resolution The sandbox mode now checks the `__toString()` method call on all objects. The patch for this issue is available [here](https://github.com/twigphp/Twig/commit/cafc608ece310e62a35a76f17e25c04ab9ed05cc) for the 3.11.x branch, and [here](https://github.com/twigphp/Twig/commit/d4a302681bca9f7c6ce2835470d53609cdf3e23e) for the 3.x branch. ### Credits We would like to thank Jamie Schouten for reporting the issue and Fabien Potencier for providing the fix.
