{"id":"GHSA-5vpg-rj7q-qpw2","summary":"Yii 2: Local file inclusion via view parameter name collision","details":"The core view rendering method `View::renderPhpFile()` calls `extract($_params_, EXTR_OVERWRITE)` before the `require` statement that includes the view file. A caller-controlled parameter named `_file_` in the `$params` array overwrites the internal local variable that specifies which file is included — enabling a Local File Inclusion primitive.\n\n### Impact\n\n- Local File Inclusion (arbitrary file read via non-PHP files)\n- Potential RCE if attacker can write PHP files via a separate primitive\n- Information disclosure\n\n### Patches\n\n2.0.55\n\n### Workarounds\n\nNo.","aliases":["CVE-2026-39850"],"modified":"2026-09-10T03:51:04.769218547Z","published":"2026-05-11T19:34:28Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-05-11T19:34:28Z","nvd_published_at":"2026-05-20T20:16:39Z","cwe_ids":["CWE-20","CWE-98"]},"references":[{"type":"WEB","url":"https://github.com/yiisoft/yii2/security/advisories/GHSA-5vpg-rj7q-qpw2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-39850"},{"type":"WEB","url":"https://github.com/yiisoft/yii2/commit/109878b491dbffa541032bc99fb5e26d12cd0375"},{"type":"PACKAGE","url":"https://github.com/yiisoft/yii2"},{"type":"WEB","url":"https://github.com/yiisoft/yii2/releases/tag/2.0.55"}],"affected":[{"package":{"name":"yiisoft/yii2","ecosystem":"Packagist","purl":"pkg:composer/yiisoft/yii2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.55"}]}],"versions":["2.0.0","2.0.0-alpha","2.0.0-beta","2.0.0-rc","2.0.1","2.0.10","2.0.11","2.0.11.1","2.0.11.2","2.0.12","2.0.12.1","2.0.12.2","2.0.13","2.0.13.1","2.0.13.2","2.0.13.3","2.0.14","2.0.14.1","2.0.14.2","2.0.15","2.0.15.1","2.0.16","2.0.16.1","2.0.17","2.0.18","2.0.19","2.0.2","2.0.20","2.0.21","2.0.22","2.0.23","2.0.24","2.0.25","2.0.26","2.0.27","2.0.28","2.0.29","2.0.3","2.0.30","2.0.31","2.0.32","2.0.33","2.0.34","2.0.35","2.0.36","2.0.37","2.0.38","2.0.39","2.0.39.1","2.0.39.2","2.0.39.3","2.0.4","2.0.40","2.0.41","2.0.41.1","2.0.42","2.0.42.1","2.0.43","2.0.44","2.0.45","2.0.46","2.0.47","2.0.48","2.0.48.1","2.0.49","2.0.49.1","2.0.49.2","2.0.49.3","2.0.49.4","2.0.5","2.0.50","2.0.51","2.0.52","2.0.53","2.0.54","2.0.6","2.0.7","2.0.8","2.0.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-5vpg-rj7q-qpw2/GHSA-5vpg-rj7q-qpw2.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
