{"id":"GHSA-7cvr-xhm5-x998","summary":"Twig Path Traversal vulnerability in the filesystem loader","details":"Twig is affected by path traversal vulnerability when used with Twig_Loader_Filesystem for loading Twig templates but only if the application is using non-trusted template names (names provided by a end-user for instance).\n\nWhen affected, it is possible to go up one directory for the paths configured in the application's loader.\n\nFor instance, if the filesystem loader is configured with /path/to/templates as a path to look for templates, an attacker can force Twig to include a file stored in /path/to by prepending the path with /../ like in {% include \"/../somefile_in_path_to\" %}\n\nNote that using anything else (like ../somefile, /../../somefile, or ../../somefile) won’t work and the application will return a proper exception.\n","modified":"2024-12-05T05:41:41.920078Z","published":"2024-05-30T13:42:49Z","database_specific":{"github_reviewed_at":"2024-05-30T13:42:49Z","nvd_published_at":null,"cwe_ids":["CWE-22"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/fabpot/Twig/commit/3d19a2eed53570776af313593aaeb5ad62cf4980.diff"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/twig/twig/2013-04-08.yaml"},{"type":"PACKAGE","url":"https://github.com/twigphp/Twig"},{"type":"WEB","url":"https://web.archive.org/web/20130511111630/http://blog.twig.sensiolabs.org/post/47461911874/security-release-twig-1-12-3-released"}],"affected":[{"package":{"name":"twig/twig","ecosystem":"Packagist","purl":"pkg:composer/twig/twig"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.0"},{"fixed":"1.12.3"}]}],"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","v1.7.0","v1.8.0","v1.8.1","v1.8.2","v1.8.3","v1.9.0","v1.9.1","v1.9.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/05/GHSA-7cvr-xhm5-x998/GHSA-7cvr-xhm5-x998.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
