CVE-2025-49438Network attack vector

Administrator-level PHP object injection

Published Aug 20, 2025 · Updated Apr 28, 2026

PHP object injection in Max Chirkov Simple Login Log 1.1.3 and earlier allows remote authenticated users to manipulate PHP objects. The CNA and Patchstack do not disclose the affected parameter, function, or serialized data source; they identify only unsafe PHP deserialization. Administrator access is required, and further effects such as code execution or data modification depend on a usable POP chain in the site's PHP classes.
