CVE-2026-15345Network attack vectorHinoki check available

Subscriber configuration tampering via unchecked causer parameter

Published Aug 16, 2026 · Updated Aug 16, 2026

Authorization bypass in ShortPixel Adaptive Images through 3.11.5 allows remote authenticated users to alter WordPress plugin settings. Notice action handlers pass the user-controlled causer value to the Notice controller, which updates option data without a capability check. Subscriber-level access is required; third-party optimizer settings are reachable only with the corresponding plugins installed, and the flaw also permits direct changes to the plugin's API key and account binding.
