Attack Vectors

CVE-2025-31928 is a medium-severity SQL Injection vulnerability (CVSS 6.5) affecting the WordPress plugin Multimedia Responsive Carousel with Image Video Audio Support (slug: multimedia-carousel) in versions 2.6.0 and below.

The attack requires an authenticated WordPress account with Contributor-level access or higher. In practical terms, this means the risk is elevated in organizations that allow guest authors, agencies, interns, or multiple internal teams to publish content—especially if any of those accounts are compromised through password reuse, phishing, or weak access controls.

Security Weakness

According to Wordfence, the plugin is vulnerable due to insufficient escaping of a user-supplied parameter and lack of sufficient preparation of an existing SQL query. This weakness can allow an authenticated attacker to append additional SQL to a database query.

Remediation is straightforward: update Multimedia Responsive Carousel with Image Video Audio Support to version 2.6.1 or newer, which contains the patch. Reference: CVE-2025-31928 record and Wordfence advisory.

Technical or Business Impacts

The primary impact is confidentiality: the CVSS vector indicates high data disclosure potential (C:H), meaning attackers may be able to extract sensitive information from the WordPress database. Depending on what’s stored, this can include user records, email addresses, password hashes, customer or lead data, and other business-critical information.

For marketing and business leaders, the downstream risk can include data breach notifications, regulatory and contractual exposure (privacy and compliance obligations), reputational damage, and loss of customer trust. Even though this issue does not indicate direct site defacement or downtime (I:N/A:N in the CVSS vector), data loss alone can create significant financial and operational impact.

Similar Attacks

SQL Injection has been a recurring root cause in major real-world incidents, including:

TalkTalk (2015) data breach — widely reported as involving SQL injection and resulting in large-scale customer data exposure.

Heartland Payment Systems breach (2008) — publicly documented as involving SQL injection and leading to significant payment card data compromise.
