CVE-2026-42473 Details
Description
Unsafe deserialization vulnerability in MixPHP Framework 2.x thru 2.2.17. The session and cache handlers use unserialize() on data from the filesystem in the FileHandler object.
A vulnerability allowing remote code execution through unsafe deserialization has been identified in MixPHP Framework versions 2.x prior to 2.2.17. The issue arises because the session and cache handlers in the FileHandler object use 'unserialize()' on data from the filesystem without any validation, allowing attacker-controlled data to be executed as code.
To address this vulnerability, update the 'unserialize()' calls to include an allowlist as the second argument, or replace 'unserialize()' with JSON serialization where object types are not necessary.
