An attacker with Subscriber-level access can manipulate this parameter to include and <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-54815-arbitrary-code-execution-via-server-side-template-injection-in-ppress-0-0-9\/\"  data-wpil-monitor-id=\"90171\">execute arbitrary<\/a> .php files on the server. This gives the attacker the ability to execute any <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-34205-critical-php-dead-code-vulnerability-in-vasion-print-virtual-appliance-host\/\"  data-wpil-monitor-id=\"89829\">PHP code<\/a> within those files.

This could be a sample HTTP request:<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/wp-admin\/admin-ajax.php?action=bei_fen_task_execute HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\ntask=..\/..\/..\/..\/malicious.php<\/code><\/pre>\n<p>In this example, the attacker sends a POST <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-44594-server-side-request-forgery-ssrf-vulnerability-in-halo-v2-20-17\/\"  data-wpil-monitor-id=\"89794\">request to the vulnerable<\/a> endpoint. The &#8216;task&#8217; parameter is exploited to include a malicious PHP <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-9693-arbitrary-file-deletion-vulnerability-in-user-meta-user-profile-builder-plugin-for-wordpress\/\"  data-wpil-monitor-id=\"90560\">file from an arbitrary<\/a> location, leading to its execution on the server.<\/p>\n<p><strong>Mitigation<\/strong><\/p>\n<p>The best way to mitigate this vulnerability is by applying the vendor-supplied patch. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation.
