Attack Vectors

The WordPress plugin MyQtip – easy qTip2 (slug: myqtip-easy-qtip2) has a Medium-severity vulnerability (CVSS 6.4, CVE-2026-1574) that can be exploited by an authenticated user with Contributor-level access or higher. An attacker can place malicious content into the plugin’s myqtip shortcode when editing posts or pages.

Because this is a stored issue, the injected script can remain embedded in your site content and run automatically when others view the affected page. This increases the likelihood of impact because the exploit does not depend on tricking a visitor into clicking a special link; it executes during normal site browsing.

Security Weakness

Versions of MyQtip – easy qTip2 up to and including 2.0.5 are vulnerable due to insufficient input sanitization and output escaping of user-supplied shortcode attributes. In practical terms, the plugin may allow unsafe content to be saved and later displayed in a way that the browser interprets as executable script.

This weakness matters for business teams because it turns normal content workflows (contributors creating or updating content) into a pathway for persistent, hard-to-detect website manipulation.

Technical or Business Impacts

This vulnerability can lead to brand and revenue risk even when the attacker has only limited editorial access. The most common outcomes include unauthorized changes to what visitors see, fraudulent lead capture, and misdirected marketing attribution (e.g., altered forms, calls-to-action, or tracking scripts on key landing pages).

For executives and compliance stakeholders, the larger concern is that scripts can be used to collect data users enter on the site (such as form details) or to stage convincing on-site prompts that damage trust. This can create downstream impacts including loss of customer confidence, campaign performance degradation, incident response and recovery costs, and potential compliance exposure if personal data is captured or mishandled.

Status and remediation: there is no known patch available per the published advisory. Organizations should assess risk and consider mitigations aligned to their tolerance; in many cases, the safest business decision is to uninstall the affected plugin and replace it, especially on high-visibility marketing sites and conversion-critical pages.

Similar attacks (real-world examples): Stored XSS issues have been repeatedly used to alter site content and run scripts in visitors’ browsers. See examples such as the WordPress core stored XSS issue fixed in WordPress 4.7.1, the jQuery XSS (CVE-2020-11022) affecting many web deployments, and a stored XSS issue in a popular WordPress plugin family like Contact Form 7’s CVE-2020-35489.
