CVE-2025-48018

Application state modification via unsafe deserialization

Published May 20, 2025 · Updated May 20, 2025

Deserialization of untrusted data in SEL-5030 acSELerator QuickSet before 7.5.2.3 allows local users to modify application state data. SEL has not published the vulnerable file, function, serialization format, or incorrect operation performed on the untrusted data. Exploitation requires a low-privileged authenticated local user, high attack complexity, and user interaction, and it can compromise application data and operation.
