CVE-2025-0428·PHP vulnerability

The "AI Power: Complete AI Pack" plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 1.8.96 via deserialization of untrusted input from the $form['post_content'] variable through the wpaicg_export_prompts function. This allows authenticated attackers, with administrative privileges, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

How to fix this CVE

Update the 'AI Power: Complete AI Pack' WordPress plugin to version 1.8.97 or later to patch the PHP Object Injection vulnerability.

WAF mitigation (if patching is not yet possible)

Add this rule to your WAF to block exploitation attempts while you schedule the patch. 

Implement strict input validation on form submissions targeting the wpaicg_export_prompts endpoint; block POST requests containing serialized PHP object patterns (e.g., 'O:' followed by numeric class length). Restrict administrative access to the export functionality via IP allowlisting or additional authentication factors.

How to check if you are affected

  1. Step 1: Check installed PHP version with: php -v
  2. Step 2: Verify the 'AI Power: Complete AI Pack' plugin version in WordPress admin > Plugins, or via SSH with: grep 'Version:' /path/to/wp-content/plugins/ai-power-complete-ai-pack/ai-power.php | head -1
  3. Step 3: Search WordPress error logs for deserialization warnings or unserialize() function calls: grep -r 'unserialize\|wpaicg_export_prompts' /var/www/html/wp-content/plugins/ai-power* /var/log/php-errors.log 2>/dev/null
  4. Step 4: Confirm plugin update by checking version again and comparing against 1.8.97: if version is 1.8.97 or higher, the fix is applied

Prior to 7.1.0, critical pre-authentication remote code execution vulnerability in ChurchCRM's setup wizard allows unauthenticated attackers to inject arbitrary PHP code during the initial installation process, leading to complete server compromise.

CVE-2025-47916CVSS 10Invision Community 5.0.0 before 5.0.7 allows remote code execution via crafted template strings to themeeditor.php. The issue lies within the themeeditor controller (file: /applications/core/modules/front/system/themeeditor.php), where a protected method named customCss can be invoked by unauthenticated users. This method passes the value of the content parameter to the Theme::makeProcessFunction() method; hence it is evaluated by the template engine. Accordingly, this can be exploited by unauthenticated attackers to inject and execute arbitrary PHP code by providing crafted template strings.
CVE-2024-5932CVSS 10The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.14.1 via deserialization of untrusted input from the 'give_title' parameter. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to execute code remotely, and to delete arbitrary files.
