Summary description

WordPress Core contains a remote file inclusion vulnerability which could allow an unauthenticated attacker to make page-template resolution include a chosen readable local `.php` file outside the active theme directories, leading to remote code execution.

Required action

Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.

Technical description

An unauthenticated attacker can make `get_page_template()` page-template resolution include a chosen readable local `.php` file outside the active theme directories. If relevant pre-conditions for both the server and the active theme are met, this can lead to RCE.

——11The Noptin – Newsletter, New Post Notifications & Email Automation plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.4.3 via the 'noptin_fields[first_name]' parameter parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included. The public Manage Preferences page issues a nonce to unauthenticated visitors, meaning there is no effective authorization barrier — an unauthenticated attacker can store the malicious payload as their first_name and have it executed the next time any newsletter is sent by the site operator. Successful exploitation additionally requires an action by an administrator — the attacker cannot trigger the vulnerability on their own.2d CVE-2026-715509.9 CRI

——10SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, the workflow controller uses a path-traversal-capable aow_action value in require_once() without constraining the resolved file. The affected flow begins at modules/AOW_WorkFlow/controller.php and uses aow_action, and require_once() to carry attacker-controlled data or authorization state into the security-sensitive operation. An authenticated user with the WorkFlow role can include executable PHP, obtain server-side code execution, access CRM data and configuration secrets, and establish persistent access. This issue is fixed in versions 7.15.2 and 8.10.2.1d CVE-2026-736958.8 HIG
