Yii 2: Local file inclusion via view parameter name collision
Packages
| Ecosystem | Package | Affected | Fixed in |

Details
As written in the advisory (Markdown source, shown as plain text).
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
2.0.55
### Workarounds
No.
