Geeky Bot EUVD-2026-27193

No special conditions - remote unauthenticated exploitation against default configurations of Geeky Bot plugin versions ≤1.2.2. The vulnerability is triggered through WordPress's standard AJAX handler (admin-ajax.php) which is always accessible on WordPress installations. No authentication, specific WordPress configuration, theme, or plugin interaction is required. The CVSS vector PR:N (privileges required: none) and UI:N (user interaction: none) confirm exploitation requires only network access to the WordPress site. The only prerequisite is that the vulnerable Geeky Bot plugin version must be installed and active. No specific WordPress permissions, non-default settings, or user actions limit exploitation. Attack succeeds against any internet-accessible WordPress site meeting the version criteria, making this maximally exploitable within the WordPress plugin ecosystem.

This vulnerability represents critical real-world risk across multiple assessment frameworks. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) indicates maximum exploitability: network-accessible, low attack complexity, no privileges required, and no user interaction needed. An automated attack could scan WordPress sites for the vulnerable plugin and achieve complete site compromise in minutes. The vulnerability enables full authentication bypass leading to RCE, placing it in the highest severity category for web application vulnerabilities. While CISA KEV status is not confirmed and public POC availability is unknown from provided data, the technical simplicity (crafted AJAX POST request → ZIP download → code execution) makes this highly automatable once discovered. EPSS score is unavailable for assessment, but the combination of WordPress plugin ecosystem exposure, unauthenticated attack vector, and direct RCE impact suggests high probability of exploitation attempts once CVE details become widely known. The Wordfence intelligence report indicates this was likely discovered through security research before widespread exploitation, making immediate patching critical. SSVC framework assessment: exploitation status unknown, technical impact total (RCE), automatable yes - priority deployment decision.

An unauthenticated attacker identifies a WordPress site running Geeky Bot ≤1.2.2 through plugin enumeration (checking /wp-content/plugins/geeky-bot/readme.txt or HTTP headers). The attacker crafts a POST request to /wp-admin/admin-ajax.php with parameters that dispatch to the plugin installation helper, specifying a URL hosting a malicious ZIP file containing a backdoor plugin. The vulnerable AJAX handler processes this request without authorization checks, downloads the ZIP from the attacker's server, and extracts it into wp-content/plugins/. The attacker then accesses the newly installed malicious plugin's PHP file directly (e.g., /wp-content/plugins/malicious-plugin/shell.php), gaining a web shell with full WordPress database access and ability to execute arbitrary system commands as the web server user.
