The vulnerability identified as EUVD-2025-26012 pertains to an "Unrestricted Upload of File with Dangerous Type" in the "Drag and Drop File Upload for Elementor Forms" plugin. This vulnerability allows an attacker to upload a web shell to a web server, which can lead to complete system compromise. The CVSS (Common Vulnerability Scoring System) base score of 10.0 indicates a critical severity level. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H breaks down as follows:

• AV:N - Attack Vector: Network
• AC:L - Attack Complexity: Low
• PR:N - Privileges Required: None
• UI:N - User Interaction: None
• S:C - Scope: Changed
• C:H - Confidentiality: High
• I:H - Integrity: High
• A:H - Availability: High

This score signifies that the vulnerability is highly exploitable and can result in severe impacts on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector involves exploiting the unrestricted file upload functionality. An attacker can upload a malicious file, such as a web shell, which can then be executed on the server. This can lead to:

• Remote Code Execution (RCE): The attacker can execute arbitrary code on the server.
• Data Exfiltration: Sensitive data can be stolen or manipulated.
• Persistent Access: The attacker can maintain long-term access to the compromised server.

Exploitation methods may include:

• Direct Upload: Using the plugin's file upload feature to upload a web shell.
• Phishing: Tricking an authorized user into uploading a malicious file.
• Automated Scripts: Using automated tools to scan for and exploit the vulnerability.

3. Affected Systems and Software Versions

The vulnerability affects the "Drag and Drop File Upload for Elementor Forms" plugin versions from n/a through 1.5.3. Any website using this plugin within the specified version range is at risk.

4. Recommended Mitigation Strategies

To mitigate this vulnerability, the following steps are recommended:

• Immediate Patching: Upgrade to a patched version of the plugin if available.
• Temporary Disabling: Disable the plugin until a patch is released.
• File Upload Restrictions: Implement server-side restrictions on file types and sizes.
• Web Application Firewall (WAF): Deploy a WAF to monitor and block suspicious uploads.
• Regular Audits: Conduct regular security audits and vulnerability assessments.
• User Education: Educate users about the risks of uploading files from untrusted sources.

5. Impact on European Cybersecurity Landscape
