CVE-2024-5649Network attack vector

Authenticated PHP object injection via gallery deserialization

Published Jun 19, 2024 · Updated Apr 8, 2026

PHP object injection in Universal Slider 1.6.5 and earlier allows remote authenticated users to inject objects through gallery input. The fsl_get_gallery_value function deserializes attacker-controlled gallery data without restricting which PHP objects can be created. Contributor access is required, and file deletion, sensitive-data retrieval, or code execution additionally requires a usable POP chain from another installed plugin or theme.
