1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2026-24960 CISA Vulnerability Name: CVE-2026-24960 Description: The vulnerability involves an unrestricted upload of files with dangerous types in the zozothemes Charety theme for WordPress. This allows attackers to upload malicious files, potentially leading to remote code execution (RCE) or other severe security issues. CVSS Score: 9.9 (Critical)

The CVSS score of 9.9 indicates a critical vulnerability. This high score is due to the potential for complete system compromise, including the execution of arbitrary code, data exfiltration, and unauthorized access to sensitive information.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unrestricted File Upload: Attackers can upload files without proper validation, leading to the execution of malicious scripts.
• Remote Code Execution (RCE): By uploading a file with executable code, attackers can gain control over the server.
• Cross-Site Scripting (XSS): Malicious files can be used to inject scripts that execute in the context of the user's browser.
• Data Exfiltration: Attackers can upload scripts to exfiltrate sensitive data from the server.

Exploitation Methods:

• Direct Upload: Attackers can directly upload a malicious file through the theme's file upload functionality.
• Phishing: Attackers can trick users into uploading malicious files through social engineering.
• Automated Scripts: Attackers can use automated scripts to scan for vulnerable installations and exploit them en masse.

3. Affected Systems and Software Versions

Affected Software:

• zozothemes Charety Theme for WordPress
• Versions: From n/a through < 2.0.2
