CVE-2026-17017 in CubeWP Framework Plugin
Summary
by MITRE • 08/09/2026
The CubeWP Framework WordPress plugin before 1.1.31 does not properly sanitize and escape a parameter before using it in a SQL statement through an AJAX action, and does not include a capability check on that action, allowing users with Subscriber-level access and above to perform SQL injection attacks.

The CubeWP Framework WordPress plugin vulnerability represents a critical security flaw that enables unauthorized SQL injection attacks through improperly sanitized input parameters. This vulnerability affects versions prior to 1131 and specifically targets the plugin's AJAX handling mechanism where user-supplied data is directly incorporated into database queries without adequate sanitization or validation. The issue stems from the lack of proper input sanitization and escaping procedures within the plugin's backend processing functions, creating an exploitable pathway for malicious actors to manipulate database operations through crafted requests.
The technical implementation of this vulnerability occurs within the plugin's AJAX action handling where a parameter is accepted from user input and subsequently used in SQL statement construction without appropriate sanitization measures. This pattern violates fundamental security principles and creates a direct injection vector that allows attackers to manipulate database queries through maliciously crafted payloads. The vulnerability exists because the plugin fails to implement proper parameter binding or input validation before executing database operations, making it susceptible to classic SQL injection techniques where attacker-controlled data can alter the intended query structure.
The operational impact of this vulnerability is significant as it lowers the attack surface for privilege escalation and data compromise. Attackers with Subscriber-level access or higher can leverage this flaw to execute arbitrary SQL commands against the WordPress database, potentially leading to data exfiltration, modification of user accounts, or even full system compromise. The capability check absence further exacerbates the risk by allowing unauthenticated or low-privilege users to trigger the vulnerable code path without proper authorization, effectively bypassing standard WordPress access controls that should prevent such operations from being executed by unauthorized parties.
This vulnerability aligns with CWE-89 which identifies SQL injection as a dangerous input validation flaw occurring when an application fails to properly escape or sanitize user-supplied data before using it in database queries. The flaw also maps to ATT&CK technique T1078 which covers valid accounts and privilege escalation through exploitation of weak access controls, as the vulnerability allows for unauthorized execution of privileged operations. Additionally, this represents a failure of the principle of least privilege and proper input validation, both fundamental concepts within cybersecurity frameworks that prevent such exploitable conditions from occurring in well-designed applications.
Mitigation strategies should focus on immediate patching to version 1131 or later where the sanitization and capability checks have been properly implemented. Administrators should also implement additional monitoring for suspicious AJAX requests and consider implementing web application firewalls to detect and block potential exploitation attempts. The remediation process should include comprehensive code review of all plugin functions that handle user input, particularly those involving database operations, with emphasis on proper parameter binding techniques and capability verification before executing privileged operations. Regular security audits and vulnerability assessments should be conducted to identify similar patterns in other plugins or custom code implementations within the WordPress ecosystem.
