CVE-2023-45271Network attack vector

Plugin settings modification via unchecked option_data_save

Published Jan 2, 2025 · Updated Apr 29, 2026

Missing authorization in WowStore 2.7.8 and earlier allows remote authenticated users to modify plugin settings via crafted requests. The option_data_save function accepts and writes option data without checking the caller's WordPress capability. Subscriber-level access is sufficient, and Patchstack reports that successful exploitation also requires privileged-user interaction with attacker-supplied content.
