CVE-2022-0188Public exploitNetwork attack vector

Unauthenticated CSS update via missing authorization

Published Feb 14, 2022 · Updated Aug 2, 2024

CMP – Coming Soon & Maintenance Plugin before 4.0.19 allows remote attackers to alter coming-soon page CSS without authentication. The vulnerable update path accepts the niteoCS_footer_background_opacity_hardwork POST value and permits injected CSS to replace the page layout. No login or other user interaction is required, so an internet-reachable WordPress site using the plugin can have its coming-soon presentation modified.
