If i look in the /XnViewMP/plugins directory i see different webp.dll_s with version 1.3.0.
Since there is an security bug (buffer overflow) in versions before 1.3.2 its recommend to update the dlls.

Re: Security problem - old webp Plugin ( CVE-2023-4863 )
Are there any plans to release XNV-MP 1.5.6 with the updated lib (Hotfix update) soon?
