CVE-2026-39850

Description

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.
