CVE-2025-67510·PHP vulnerability

Neuron is a PHP framework for creating and orchestrating AI Agents. In versions 2.8.11 and below, the MySQLWriteTool executes arbitrary SQL provided by the caller using PDO::prepare() + execute() without semantic restrictions. This is consistent with the name (“write tool”), but in an LLM/agent context it becomes a high-risk capability: prompt injection or indirect prompt manipulation can cause execution of destructive queries such as DROP TABLE, TRUNCATE, DELETE, ALTER, or privilege-related statements (subject to DB permissions). Deployments that expose an agent with MySQLWriteTool enabled to untrusted input and/or run the tool with a DB user that has broad privileges are impacted. This issue is fixed in version 2.8.12.

How to fix this CVE

Organizations using the Neuron PHP framework must upgrade to version 2.8.12 or later to mitigate SQL injection risks from the MySQLWriteTool component. If your AI agents expose database write capabilities to untrusted input or operate with overly permissive database credentials, prioritize this patch immediately. Additionally, review database user permissions to follow the principle of least privilege and restrict agent tool access to read-only operations where possible.

sudo dnf update php

WAF mitigation (if patching is not yet possible)

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

Implement WAF rules to detect and block requests containing SQL keywords (DROP TABLE, TRUNCATE, ALTER TABLE, GRANT, REVOKE) in parameters sent to endpoints that invoke MySQLWriteTool. Monitor for unusual database modification requests originating from AI agent processing endpoints and enforce query whitelisting at the application level.

How to check if you are affected

  1. Step 1: Check PHP version with `php -v` and verify if Neuron framework is installed by checking `composer show neuron-core/neuron-ai` in your project root
  2. Step 2: Search your codebase for MySQLWriteTool instantiation: `grep -r 'MySQLWriteTool' /path/to/app/`
  3. Step 3: Review database logs for suspicious DROP TABLE, TRUNCATE, DELETE, ALTER, or GRANT statements from unexpected sources using `grep -i 'drop table\|truncate\|alter table' /var/log/mysql/error.log`
  4. Step 4: Verify the fix by confirming Neuron version 2.8.12+ is installed with `composer show neuron-core/neuron-ai | grep Version`

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.
CVE-2026-39337CVSS 10ChurchCRM is an open-source church management system. 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. The "$dbPassword" variable is not sanitized. This vulnerability exists due to an incomplete fix for CVE-2025-62521. This vulnerability is fixed in 7.1.0.
CVE-2025-62521CVSS 10ChurchCRM is an open-source church management system. Prior to version 5.21.0, a 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. The vulnerability exists in `setup/routes/setup.php` where user input from the setup form is directly concatenated into a PHP configuration template without any validation or sanitization. Any parameter in the setup form can be used to inject PHP code that gets written to `Include/Config.php`, which is then executed on every page load. This is more severe than typical authenticated RCE vulnerabilities because it requires no credentials and affects the installation process that administrators must complete. Version 5.21.0 patches the issue.

CVE-2026-28289CVSS 10FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. A patch bypass vulnerability for CVE-2026-27636 in FreeScout 1.8.206 and earlier allows any authenticated user with file upload permissions to achieve Remote Code Execution (RCE) on the server by uploading a malicious .htaccess file using a zero-width space character prefix to bypass the security check. The vulnerability exists in the sanitizeUploadedFileName() function in app/Http/Helper.php. The function contains a Time-of-Check to Time-of-Use (TOCTOU) flaw where the dot-prefix check occurs before sanitization removes invisible characters. This vulnerability is fixed in 1.8.207.
