CVE-2026-15215 in Subscriptions for WooCommerce Plugin
Summary
by MITRE • 08/07/2026
The Subscriptions for WooCommerce WordPress plugin before 2.0.1 does not verify the user's capability before installing and activating a Subscriptions for WooCommerce WordPress plugin before 2.0.1 from a user-supplied slug through a nonce-protected AJAX action, allowing users with the Shop Manager role (who lack Subscriptions for WooCommerce WordPress plugin before 2.0.1-management capabilities) to install and activate arbitrary Subscriptions for WooCommerce WordPress plugin before 2.0.1, resulting in remote code execution.

The vulnerability in the Subscriptions for WooCommerce WordPress plugin affects versions prior to 2.0.1 and represents a critical privilege escalation flaw that undermines the plugin's security model. This issue stems from inadequate capability verification within the plugin's AJAX handling mechanism, specifically when processing user-supplied slugs for plugin installation and activation operations. The flaw allows users with the Shop Manager role to bypass normal access controls and execute unauthorized actions that should be restricted to administrators or users with proper privileges.
The technical implementation of this vulnerability occurs through a nonce-protected AJAX action that processes plugin slugs provided by users without performing adequate user capability checks. This design flaw creates an attack vector where malicious actors with Shop Manager privileges can manipulate the plugin installation process to install and activate arbitrary plugins from remote sources. The absence of proper access control validation means that legitimate security boundaries are circumvented, allowing unauthorized code execution within the WordPress environment.
From an operational impact perspective, this vulnerability transforms a relatively low-privilege user account into a potential vector for complete system compromise. Shop Manager roles typically have limited administrative capabilities but can now leverage this flaw to install malicious plugins that may contain backdoors, malware, or other exploit payloads. The remote code execution capability provides attackers with persistent access to the WordPress installation, potentially enabling data exfiltration, lateral movement within network infrastructure, or further exploitation of connected systems.
The vulnerability aligns with CWE-284 (Improper Access Control) and maps to attack techniques in the MITRE ATT&CK framework under T1059 (Command and Scripting Interpreter) and T1078 (Valid Accounts). This weakness creates a persistent threat vector that can be exploited for long-term system compromise, particularly when combined with other vulnerabilities or through social engineering attacks that might grant initial access to Shop Manager accounts.
Effective mitigations for this vulnerability include immediate patching to version 2.0.1 or later, which implements proper capability verification mechanisms. Administrators should also implement additional security controls such as restricting AJAX access to trusted IP ranges, monitoring plugin installation activities through logging and alerting systems, and regularly auditing user roles and capabilities within the WordPress environment. Network segmentation and application firewalls can provide additional layers of protection against exploitation attempts. The vulnerability demonstrates the critical importance of proper access control implementation in WordPress plugins and highlights the need for comprehensive security testing of all user-facing administrative functions.
