WordPress sites using GutenKit and Hunk Companion are facing actively exploited plugin-install flaws tracked as CVE-2024-9234, CVE-2024-9707, and CVE-2024-11972. The critical (CVSS 9.8) issues let attackers install arbitrary plugins and can lead to remote code execution (RCE).

Defenders are told to watch for specific request paths and rogue directories, and to keep plugins updated.

    Wordfence blocks 8.7 million attacks against vulnerable WordPress plugins

    Exploitation Observed

    On October 24, 2025, Wordfence said it blocked 8.7 million attack attempts against WordPress sites using GutenKit and Hunk Companion over October 8 and 9, as a widespread exploitation campaign abused CVE-2024-9234, CVE-2024-9707, and CVE-2024-11972 to install arbitrary plugins and enable RCE. Researchers also tied the campaign to a GitHub-hosted malicious plugin archive called 'up' and advised defenders to watch for /wp-json/gutenkit/v1/install-active-plugin, /wp-json/hc/v1/themehunk-import, /up, /background-image-cropper, /ultra-seo-processor-wp, /oke, and /wp-query-console.
