Attack Vectors

CVE-2025-31640 is a Medium-severity SQL Injection vulnerability (CVSS 6.5, CVE record) affecting the Magic Responsive Slider and Carousel WordPress plugin (slug: magic-carousel) in versions <= 1.4.

The key risk factor is that the attack is authenticated: an attacker needs a valid WordPress account with at least Contributor permissions (or higher). In many organizations, Contributor access is given to marketing staff, agencies, freelancers, or multiple internal users to publish or stage content—expanding the practical exposure beyond “admins only.”

The CVSS vector (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) indicates the attack can be performed remotely over the network, is relatively easy to execute once logged in, does not require a user to click anything, and primarily threatens confidentiality (data exposure).

Security Weakness

This issue is caused by insufficient escaping of a user-supplied parameter combined with insufficient preparation of an SQL query. In practical terms, the plugin can allow an authenticated user to manipulate a database query in ways the site owner did not intend.

Because the weakness is tied to database query handling, it can enable an attacker to append additional SQL into existing queries and potentially extract sensitive information from the WordPress database.

Technical or Business Impacts

While the severity is rated Medium, the potential business impact can be significant because the vulnerability’s CVSS indicates high confidentiality impact. Possible outcomes include unauthorized access to data stored in the database (depending on what the vulnerable query can reach), which may include information that supports your marketing operations, customer engagement, or site administration.

For business leaders and compliance teams, the most immediate concerns are data exposure risk, potential privacy and regulatory obligations if sensitive records are accessed, and the reputational damage that can follow a disclosure. This type of issue is also commonly used as a stepping stone during broader attacks—where a “lower-privilege” account (like a Contributor) is leveraged to gain deeper insight into the environment.

Remediation: Update Magic Responsive Slider and Carousel WordPress to version 1.6 or a newer patched version, as recommended by the published advisory (source).
