CVE-2025-31424 is a critical SQL Injection vulnerability identified in the WordPress plugin 'WP Lead Capturing Pages' developed by kamleshyadav. This vulnerability arises from improper neutralization of special elements used in SQL commands (CWE-89), allowing an attacker to perform Blind SQL Injection attacks. Blind SQL Injection occurs when an attacker can send malicious SQL queries to the backend database but does not receive direct feedback from the database responses, instead inferring information based on application behavior or timing. The vulnerability affects all versions of the plugin up to and including version 2.3. The CVSS v3.1 base score is 9.3, indicating a critical severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L) shows that the attack can be performed remotely over the network without any authentication or user interaction, with low attack complexity. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality is high, as attackers can extract sensitive data from the backend database, but integrity is not impacted, and availability impact is low. No patches or fixes have been published yet, and no known exploits are reported in the wild. However, given the nature of SQL Injection vulnerabilities, exploitation could lead to unauthorized data disclosure, potentially exposing sensitive customer or business information collected via the lead capturing pages. This vulnerability is particularly dangerous because it requires no authentication and can be exploited remotely, making it an attractive target for attackers seeking to extract data from vulnerable WordPress sites using this plugin.

For European organizations using the WP Lead Capturing Pages plugin, this vulnerability poses a significant risk to the confidentiality of their data. Lead capturing pages often collect personally identifiable information (PII), contact details, and other sensitive customer data. Exploitation could lead to unauthorized disclosure of this information, violating GDPR and other data protection regulations prevalent in Europe, potentially resulting in legal penalties and reputational damage. The critical severity and ease of exploitation mean attackers could automate attacks against vulnerable sites, leading to widespread data breaches. Additionally, the change in scope implies that the vulnerability could affect other components or services connected to the plugin, potentially increasing the attack surface. Although no integrity or availability impacts are noted, the loss of confidentiality alone is severe given the nature of data handled. Organizations relying on this plugin for marketing or customer engagement should consider the risk of data leakage and the potential for attackers to leverage extracted data for phishing or further attacks.

Given the absence of an official patch, European organizations should take immediate proactive steps to mitigate risk. First, they should audit their WordPress installations to identify if the WP Lead Capturing Pages plugin is installed and determine the version in use. If the plugin is present and unpatched, organizations should consider disabling or uninstalling it temporarily to eliminate exposure. Alternatively, restricting access to the plugin's endpoints via web application firewalls (WAFs) or IP whitelisting can reduce attack surface. Implementing strict input validation and parameterized queries at the application level can help, but this requires code changes by the vendor. Monitoring web server logs for suspicious SQL injection patterns or anomalous requests targeting the plugin's URLs is also recommended. Organizations should prepare to apply patches promptly once released by the vendor. Additionally, conducting regular security assessments and penetration testing focusing on SQL injection vectors can help detect exploitation attempts. Finally, ensuring that backups are current and secure will aid recovery if data compromise occurs.
