CVE-2025-53468 is a high-severity SQL Injection vulnerability (CWE-89) affecting the Wp tabber widget developed by gopiplus@hotmail.com. The vulnerability arises from improper neutralization of special elements in SQL commands, allowing an attacker with low privileges (PR:L) to execute crafted SQL queries remotely (AV:N) without requiring user interaction (UI:N). The vulnerability impacts the confidentiality of the database, enabling unauthorized data disclosure, while integrity and availability impacts are limited or not evident. The vulnerability affects all versions of the Wp tabber widget up to version 4.0, though exact affected versions are unspecified. The CVSS 3.1 vector (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L) indicates that exploitation is relatively easy due to low attack complexity and no user interaction, but requires some level of privilege, such as a low-privileged authenticated user. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component, potentially impacting the broader system or database. No patches or known exploits in the wild have been reported as of the publication date (2025-09-22). The vulnerability is critical for environments where the Wp tabber widget is deployed, especially in WordPress sites that rely on this plugin for tabbed content display. Exploitation could lead to unauthorized disclosure of sensitive data stored in the backend database, which may include user credentials, personal data, or business-critical information. Given the nature of SQL Injection, attackers could also potentially escalate their privileges or pivot to other attacks if combined with other vulnerabilities.

For European organizations, the impact of CVE-2025-53468 can be significant, especially for those using WordPress sites with the Wp tabber widget installed. The vulnerability allows attackers to extract sensitive data from backend databases, potentially violating GDPR and other data protection regulations due to unauthorized access to personal data. This could lead to legal penalties, reputational damage, and loss of customer trust. Additionally, the compromise of website data integrity or confidentiality could disrupt business operations, particularly for e-commerce, financial services, healthcare, and government sectors that rely heavily on web presence and data security. The changed scope of the vulnerability means that the attack could affect multiple components or databases, increasing the risk of widespread data leakage. Although no known exploits are reported yet, the ease of exploitation and high impact on confidentiality make it a critical risk that European organizations must address proactively.

1. Immediate audit and inventory of all WordPress installations to identify the presence of the Wp tabber widget, especially versions up to 4.0. 2. Since no official patch is currently available, implement web application firewall (WAF) rules to detect and block SQL Injection attempts targeting the widget's input parameters. 3. Restrict access to the WordPress admin and widget configuration interfaces to trusted users only, minimizing the risk of low-privileged user exploitation. 4. Employ parameterized queries and prepared statements in any custom code interacting with the widget or its database components if customization is present. 5. Monitor web server and database logs for unusual query patterns or error messages indicative of SQL Injection attempts. 6. Plan for rapid deployment of official patches or updates from the vendor once available. 7. Educate site administrators and developers on secure coding practices and the risks associated with SQL Injection vulnerabilities. 8. Consider isolating the WordPress environment or database with strict access controls and network segmentation to limit potential lateral movement in case of exploitation.
