{"id":"GHSA-6377-hfv9-hqf6","summary":"Twig has unguarded calls to `__toString()` when nesting an object into an array","details":"### Description\n\nIn 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).\n\n### Resolution\n\nThe sandbox mode now checks the `__toString()` method call on all objects.\n\nThe 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.\n\n### Credits\n\nWe would like to thank Jamie Schouten for reporting the issue and Fabien Potencier for providing the fix.","aliases":["CVE-2024-51754"],"modified":"2025-05-29T21:34:35.218736Z","published":"2024-11-06T19:52:31Z","database_specific":{"cwe_ids":["CWE-668"],"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2024-11-06T19:52:31Z","nvd_published_at":"2024-11-06T20:15:05Z"},"references":[{"type":"WEB","url":"https://github.com/twigphp/Twig/security/advisories/GHSA-6377-hfv9-hqf6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-51754"},{"type":"WEB","url":"https://github.com/twigphp/Twig/commit/2bb8c2460a2c519c498df9b643d5277117155a73"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/twig/twig/CVE-2024-51754.yaml"},{"type":"PACKAGE","url":"https://github.com/twigphp/Twig"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00039.html"},{"type":"WEB","url":"https://symfony.com/blog/unguarded-calls-to-__tostring-when-nesting-an-object-into-an-array"}],"affected":[{"package":{"name":"twig/twig","ecosystem":"Packagist","purl":"pkg:composer/twig/twig"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.11.2"}]}],"versions":["1.3.0","1.4.0","1.5.0","1.5.1","1.6.0","1.6.1","1.6.2","1.6.3","1.6.4","1.6.5","v1.10.0","v1.10.1","v1.10.2","v1.10.3","v1.11.0","v1.11.1","v1.12.0","v1.12.0-RC1","v1.12.1","v1.12.2","v1.12.3","v1.13.0","v1.13.1","v1.13.2","v1.14.0","v1.14.1","v1.14.2","v1.15.0","v1.15.1","v1.16.0","v1.16.1","v1.16.2","v1.16.3","v1.17.0","v1.18.0","v1.18.1","v1.18.2","v1.19.0","v1.20.0","v1.21.0","v1.21.1","v1.21.2","v1.22.0","v1.22.1","v1.22.2","v1.22.3","v1.23.0","v1.23.1","v1.23.2","v1.23.3","v1.24.0","v1.24.1","v1.24.2","v1.25.0","v1.26.0","v1.26.1","v1.27.0","v1.28.0","v1.28.1","v1.28.2","v1.29.0","v1.30.0","v1.31.0","v1.32.0","v1.33.0","v1.33.1","v1.33.2","v1.34.0","v1.34.1","v1.34.2","v1.34.3","v1.34.4","v1.35.0","v1.35.1","v1.35.2","v1.35.3","v1.35.4","v1.36.0","v1.37.0","v1.37.1","v1.38.0","v1.38.1","v1.38.2","v1.38.3","v1.38.4","v1.39.0","v1.39.1","v1.40.0","v1.40.1","v1.41.0","v1.42.0","v1.42.1","v1.42.2","v1.42.3","v1.42.4","v1.42.5","v1.43.0","v1.43.1","v1.44.0","v1.44.1","v1.44.2","v1.44.3","v1.44.4","v1.44.5","v1.44.6","v1.44.7","v1.44.8","v1.7.0","v1.8.0","v1.8.1","v1.8.2","v1.8.3","v1.9.0","v1.9.1","v1.9.2","v2.0.0","v2.1.0","v2.10.0","v2.11.0","v2.11.1","v2.11.2","v2.11.3","v2.12.0","v2.12.1","v2.12.2","v2.12.3","v2.12.4","v2.12.5","v2.13.0","v2.13.1","v2.14.0","v2.14.1","v2.14.10","v2.14.11","v2.14.12","v2.14.13","v2.14.2","v2.14.3","v2.14.4","v2.14.5","v2.14.6","v2.14.7","v2.14.8","v2.14.9","v2.15.0","v2.15.1","v2.15.2","v2.15.3","v2.15.4","v2.15.5","v2.15.6","v2.16.0","v2.16.1","v2.2.0","v2.3.0","v2.3.1","v2.3.2","v2.4.0","v2.4.1","v2.4.2","v2.4.3","v2.4.4","v2.4.5","v2.4.6","v2.4.7","v2.4.8","v2.5.0","v2.6.0","v2.6.1","v2.6.2","v2.7.0","v2.7.1","v2.7.2","v2.7.3","v2.7.4","v2.8.0","v2.8.1","v2.9.0","v3.0.0","v3.0.0-BETA1","v3.0.1","v3.0.2","v3.0.3","v3.0.4","v3.0.5","v3.1.0","v3.1.1","v3.10.0","v3.10.1","v3.10.2","v3.10.3","v3.11.0","v3.11.1","v3.2.1","v3.3.0","v3.3.1","v3.3.10","v3.3.2","v3.3.3","v3.3.4","v3.3.5","v3.3.6","v3.3.7","v3.3.8","v3.3.9","v3.4.0","v3.4.1","v3.4.2","v3.4.3","v3.5.0","v3.5.1","v3.6.0","v3.6.1","v3.7.0","v3.7.1","v3.8.0","v3.9.0","v3.9.1","v3.9.2","v3.9.3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/11/GHSA-6377-hfv9-hqf6/GHSA-6377-hfv9-hqf6.json"}},{"package":{"name":"twig/twig","ecosystem":"Packagist","purl":"pkg:composer/twig/twig"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.12"},{"fixed":"3.14.1"}]}],"versions":["v3.12.0","v3.13.0","v3.14.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/11/GHSA-6377-hfv9-hqf6/GHSA-6377-hfv9-hqf6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
