CVE-2026-39850

Yii 2 is a PHP application framework. Versions 2.0.54 and prior contain flawed logic in the core view rendering method View::renderPhpFile() that leads to Local File Inclusion. The function calls extract($params, EXTR_OVERWRITE) before the require statement that loads the view file. As a result, a caller-controlled file key in the $params array overwrites the internal local variable specifying which file to include, potentially enabling RCE if an attacker can write PHP files through a separate primitive, as well as information disclosure. This issue has been fixed in version 2.0.55.

This issue has been fixed in version 2.0.55.

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.

Impact

• Local File Inclusion (arbitrary file read via non-PHP files)
• Potential RCE if attacker can write PHP files via a separate primitive
• Information disclosure

Patches

Workarounds

No.
