1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified as EUVD-2025-3546 pertains to an SQL Injection flaw in the NotFound WordPress Local SEO plugin. This vulnerability allows for Blind SQL Injection, which is a severe type of SQL Injection where the attacker does not receive direct feedback from the database but can infer information through indirect means.

Severity Evaluation:

• Base Score: 9.3 (Critical)
• Base Score Version: CVSS:3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L

The CVSS score of 9.3 indicates a critical vulnerability. The vector breakdown shows:

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

This high score underscores the potential for significant impact on confidentiality, with a low barrier to exploitation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Given the attack vector is network-based, an attacker can exploit this vulnerability remotely without needing local access.
• Blind SQL Injection: The attacker can inject malicious SQL queries into the application through input fields, URL parameters, or other user-controlled data points.

Exploitation Methods:

• Inference Techniques: The attacker can use techniques such as time-based or error-based inference to extract information from the database.
• Automated Tools: Utilizing automated SQL Injection tools like sqlmap or manual crafting of SQL queries to exploit the vulnerability.

3. Affected Systems and Software Versions

Affected Software:

• WordPress Local SEO Plugin
• Versions: n/a through 2.3

Affected Systems:

• Any WordPress installation using the NotFound Local SEO plugin within the specified version range.
