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."}], "lastModified": "2026-06-13T03:16:19.573", "sourceIdentifier": "security@wordfence.com"}
