Attack Vectors

CVE-2026-1512 affects the WordPress plugin Essential Addons for Elementor – Popular Elementor Templates & Widgets (slug: essential-addons-for-elementor-lite) in versions up to and including 6.5.9. It is rated Medium severity (CVSS 6.4).

The attack requires an authenticated WordPress account with at least Contributor access (or higher). An attacker in that role can place malicious script content into pages using the plugin’s Info Box widget. Because this is a stored cross-site scripting issue, the malicious content can execute later when someone views the affected page.

This risk is particularly relevant for organizations that allow multiple users to create or edit content (marketing teams, agencies, contractors, or regional site editors), where contributor-level access is common.

Security Weakness

The vulnerability is a Stored Cross-Site Scripting (XSS) weakness caused by insufficient input sanitization and output escaping of user-supplied attributes in the Info Box widget. In practical terms, this means the plugin does not adequately prevent untrusted content from being saved and then rendered to site visitors.

Because the stored content runs in the visitor’s browser in the context of your site, it can appear indistinguishable from legitimate site behavior. The CVSS vector indicates the issue is network-accessible, low complexity, and requires low privileges (Contributor+), with potential impact spanning beyond the immediate component due to how injected content can affect other users’ sessions.

Technical or Business Impacts

For business leaders, the primary risk is that a malicious contributor account (or an account taken over through phishing or password reuse) could inject scripts that run for every visitor or staff member who views an affected page. That can translate into compromised trust and brand damage, especially if the injected content defaces pages, redirects visitors, or displays fraudulent offers.

Operationally, this can create incident-response overhead for marketing and IT teams: emergency content takedowns, site integrity checks, forced password resets, and potential downtime for campaign landing pages. If the injected scripts target staff users who have higher privileges, the situation can escalate into broader site compromise.

From a compliance and risk perspective, stored XSS can be used to capture sensitive information entered into forms or to interfere with customer interactions. Even if the direct confidentiality and integrity impact is rated limited in the CVSS score, the downstream consequences (loss of customer confidence, campaign disruption, and potential reporting obligations depending on what data is exposed) can be materially significant.

Remediation: Update Essential Addons for Elementor – Popular Elementor Templates & Widgets to version 6.5.10 or a newer patched version. Reference: CVE-2026-1512 and the vendor advisory details via Wordfence: Wordfence vulnerability record.
