WS Optimize – All-in-One Speed Booster & Cache Tools <= 3.3.19 - Authenticated (Editor+) Arbitrary File Read_CVE-2026-12089

{
    "lastseen": "",
    "description": "The LWS Optimize \u2013 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.",
