An authenticated SQL injection vulnerability in the CubeWP Framework plugin allows low-privileged users to execute unauthorized database queries.

The vulnerability stems from improper sanitization and a lack of capability checks on an AJAX action, which allows users with Subscriber-level access to inject malicious SQL commands.

A successful SQL injection attack can lead to unauthorized data disclosure, modification of sensitive information, or complete database compromise. The CVSS score of 8.1 reflects the potential for significant impact on data confidentiality and integrity, which could result in regulatory non-compliance and loss of consumer trust.

Immediate Action: Update the CubeWP Framework plugin to version 1.1.31 or later to resolve the input sanitization flaw.

Proactive Monitoring: Monitor database query logs for evidence of SQL injection patterns or unexpected data retrieval attempts from Subscriber accounts.

Compensating Controls: Use a Web Application Firewall with SQL injection protection rules to filter malicious payloads directed at WordPress AJAX endpoints.

Public Exploit Available: Yes, a public proof-of-concept exists.

The presence of a public proof-of-concept elevates the risk profile of this vulnerability. Organizations using the CubeWP Framework must apply the 1.1.31 update immediately to prevent potential exploitation of the database.
