Attack Vectors

CVE-2025-31641 is a Medium-severity SQL Injection vulnerability (CVSS 6.5, CVE record) affecting the UberSlider WordPress plugin (slug: uber-classic) in versions before 2.6.

This issue can be exploited by an authenticated WordPress user with Contributor-level access (or higher). In practical business terms, that means the risk increases if an attacker can obtain low-level credentials through password reuse, phishing, or a compromised contributor account from an agency, contractor, or former employee.

Because this is a network-accessible (AV:N) issue that does not require user interaction (UI:N), it can be triggered quietly once an attacker has the required login level.

Security Weakness

According to the published advisory, UberSlider is vulnerable due to insufficient escaping of a user-supplied parameter and lack of sufficient preparation in an existing SQL query in versions up to, but not including, 2.6.

This weakness can allow an authenticated attacker to append additional SQL to an existing database query and extract sensitive information from the WordPress database. The CVSS vector also reflects this with a high confidentiality impact (C:H) and no stated integrity or availability impact.

Remediation: Update UberSlider to version 2.6 (or a newer patched version). Source: Wordfence vulnerability advisory.

Technical or Business Impacts

The primary risk is data exposure. If exploited, attackers may be able to retrieve sensitive records stored in the WordPress database. Depending on what your site stores, that could include business contact data, operational information, or other confidential content associated with your WordPress environment.

For business owners and compliance teams, the key impacts typically include:

1) Compliance and reporting pressure: Potential exposure of personal data can trigger internal incident-response procedures and, depending on jurisdiction and data type, regulatory or contractual notification obligations.

2) Brand and revenue risk: Even without visible website downtime, data leakage can damage customer trust, disrupt campaigns, and create downstream costs (forensics, legal review, PR, and additional security controls).

3) Increased likelihood of broader compromise: While this specific issue is about database querying, leaked data can help attackers expand access (for example, by learning usernames, emails, site structure, or other details that make follow-on attacks more effective).
