CVE-2023-6528Public exploitNetwork attack vector

Authenticated code execution via slider import deserialization

Published Jan 8, 2024 · Updated Jun 3, 2025

Insecure deserialization in Slider Revolution before 6.6.19 allows remote authenticated users to execute code via a crafted slider import. The import handler unserializes attacker-controlled objects from custom_animations.txt inside an uploaded slider archive. An Author account with plugin-settings access is required, and successful exploitation runs arbitrary commands in the WordPress server context.
