CVE-2025-58255

Unknown · Unknown Multiple Products (specifically the "Custom Post Type Images" component)

A critical vulnerability has been identified in multiple products utilizing the "Custom Post Type Images" component, which could allow an attacker to take complete control of affected systems.

Executive summary

A critical vulnerability has been identified in multiple products utilizing the "Custom Post Type Images" component, which could allow an attacker to take complete control of affected systems. This flaw, tracked as CVE-2025-58255, enables an attacker to inject and execute malicious code by tricking an authenticated user into performing an unintended action. Due to its critical severity rating, immediate remediation is required to prevent potential system compromise and data breaches.

Vulnerability

The vulnerability is a Cross-Site Request Forgery (CSRF) that leads to Code Injection. An attacker can craft a malicious link or web page and trick a logged-in administrator of the vulnerable application into clicking it. When the administrator visits the malicious page, their browser automatically sends a request to the vulnerable application, which the application trusts because the user is authenticated. This forged request can be used to inject and execute arbitrary code on the server, leading to a full system compromise.

Business impact

This vulnerability is rated as critical severity with a CVSS score of 9.6. Successful exploitation could lead to a complete compromise of the affected server's confidentiality, integrity, and availability. An attacker could steal sensitive data, deploy ransomware, deface websites, or use the compromised system as a pivot point to attack other internal network resources. The potential business impact includes significant financial loss, reputational damage, regulatory fines, and disruption of business operations.

Remediation

Immediate Action: The primary remediation is to apply vendor-supplied patches immediately. Organizations should update all instances of "Unknown Multiple Products" that use the vulnerable "Custom Post Type Images" component to the latest available version that addresses this flaw.

Proactive Monitoring: After patching, security teams should monitor for any signs of compromise. Review web server access logs and application logs for unusual or malformed requests targeting the application's administrative functions. Monitor for unexpected outbound network connections, unauthorized file modifications, or the creation of suspicious user accounts on the affected systems.

Compensating Controls: If immediate patching is not feasible, implement compensating controls to reduce risk. This includes deploying a Web Application Firewall (WAF) with rules designed to detect and block CSRF and code injection attacks. Additionally, enforce strict access controls and ensure administrative users log out of their sessions when not in use to minimize the window of opportunity for an attacker.

Exploitation status

Public Exploit Available: Not known at this time

Analyst recommendation

Given the critical CVSS score of 9.6, this vulnerability poses a severe risk to the organization. We strongly recommend that all affected systems be patched on an emergency basis. Although there is no evidence of active exploitation and it is not on the CISA KEV list, the potential for complete system compromise necessitates immediate action. If patching is delayed for any reason, the compensating controls outlined above must be implemented without delay to mitigate the immediate threat.
