Description

AI Translation Available

The LWS Optimize – All-in-One Speed Booster & Cache Tools plugin for WordPress is vulnerable to Arbitrary File Read in versions up to, and including, 3.3.19. This is due to the combine_current_css() function trusting <link rel='stylesheet' href='...'> values harvested from page HTML and converting same-site URLs to absolute filesystem paths before reading them with file_get_contents()/Minify\CSS::add(), without enforcing that the resolved path stay within ABSPATH or have a .css extension. This makes it possible for authenticated attackers, with Editor-level access and above, to read arbitrary files.
