CVE-2025-10726

Comprehensive Technical Analysis of CVE-2025-10726

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-10726 CVSS Score: 9.1

The vulnerability in the WPRecovery plugin for WordPress is classified as a SQL Injection vulnerability. The CVSS score of 9.1 indicates a critical severity level. This high score is due to the potential for unauthenticated attackers to execute arbitrary SQL queries and delete arbitrary files on the server, leading to significant data breaches and system compromises.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: The primary attack vector is SQL Injection via the 'data[id]' parameter. Attackers can manipulate this parameter to inject malicious SQL code.
• File Deletion: The SQL injection can be leveraged to pass file paths to PHP's unlink() function, allowing attackers to delete arbitrary files on the server.

Exploitation Methods:

• Data Exfiltration: Attackers can extract sensitive information from the database by appending additional SQL queries.
• File Deletion: By injecting file paths through the SQL query, attackers can delete critical system files, leading to denial of service or further system compromise.

3. Affected Systems and Software Versions

Affected Software:

• WPRecovery plugin for WordPress

Affected Versions:

• All versions up to and including 2.0

Impacted Systems:

• Any WordPress installation using the WPRecovery plugin versions up to 2.0.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update the Plugin: Ensure that the WPRecovery plugin is updated to a version that addresses this vulnerability.
• Disable the Plugin: If an update is not available, consider disabling the plugin until a secure version is released.

Long-Term Mitigations:

• Input Validation: Implement robust input validation and sanitization for all user-supplied parameters.
• Prepared Statements: Use prepared statements and parameterized queries to prevent SQL injection.
• Least Privilege: Ensure that the database user has the minimum necessary permissions.
• Regular Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.

5. Impact on Cybersecurity Landscape

The discovery of this vulnerability highlights the ongoing risk of SQL injection attacks, particularly in web applications. It underscores the importance of secure coding practices and regular updates to mitigate such risks. The potential for unauthenticated attackers to exploit this vulnerability emphasizes the need for continuous monitoring and proactive security measures.

6. Technical Details for Security Professionals

Vulnerability Details:

• Parameter: 'data[id]'
• Issue: Insufficient escaping and lack of preparation on the SQL query.
• Impact: Allows appending additional SQL queries and passing file paths to PHP's unlink() function.

Code Analysis:

• Vulnerable Code:

  $id = $_GET['data[id]'];
  $query = "SELECT * FROM backups WHERE id = $id";
  $result = mysqli_query($connection, $query);
  

• Secure Code:

  $id = $_GET['data[id]'];
  $stmt = $connection->prepare("SELECT * FROM backups WHERE id = ?");
  $stmt->bind_param("i", $id);
  $stmt->execute();
  $result = $stmt->get_result();
