The InPost Gallery WordPress plugin before 2.1.4.1 insecurely uses PHP's extract() function when rendering HTML views, allowing attackers to force the inclusion of malicious files & URLs, which may enable them to run code on servers.
The InPost Gallery WordPress plugin, in versions < 2.2.2, is affected by a reflected cross-site scripting vulnerability in the 'imgurl' parameter to the addinpostgalleryslideitem action, which can only be triggered by an authenticated user.
