Attack Vectors

Disable Admin Notices – Hide Dashboard Notifications (slug: disable-admin-notices) has a Medium-severity vulnerability (CVSS 4.3) tracked as CVE-2026-2410. The issue can be exploited over the web when an attacker tricks a logged-in WordPress administrator into interacting with a crafted link or page.

This is a Cross-Site Request Forgery (CSRF) scenario: the attacker does not need to log in, but relies on the administrator already being authenticated in the browser. If the administrator is persuaded to click, the attacker can cause an unauthorized settings change in the plugin.

Security Weakness

The vulnerability exists in all versions up to and including 1.4.2 due to missing nonce validation in the plugin’s showPageContent() function. In practical terms, the plugin does not sufficiently verify that a settings-change request was intentionally initiated by a legitimate admin action inside your WordPress dashboard.

As reported, this can allow an unauthenticated attacker to add arbitrary URLs to the blocked redirects list via a forged request, provided they can induce an administrator to perform an action such as clicking a link.

Technical or Business Impacts

While this vulnerability is not described as exposing sensitive data (CVSS indicates no confidentiality impact), it can still create meaningful business risk by enabling unauthorized configuration changes that affect how the site behaves.

Potential business impacts include:

1) Disrupted marketing and conversion flows: If legitimate destinations are added to a blocked redirects list, users may be prevented from reaching key pages (campaign landing pages, signup flows, checkout paths), reducing conversion rates.
2) Brand and trust impact: Unexpected redirect behavior or broken navigation can create a perception that the site is unreliable or compromised.
3) Operational overhead: Time spent diagnosing “mysterious” site behavior and reversing settings changes can pull resources away from revenue-generating work.
4) Governance and compliance concerns: Unauthorized admin-level configuration changes—especially those affecting user routing—can complicate change-control expectations and audit readiness.

Remediation: Update Disable Admin Notices – Hide Dashboard Notifications to version 1.4.3 or newer (patched). After updating, review the plugin’s settings—especially any redirect-blocking lists—for unexpected entries and remove anything you do not recognize.

Similar Attacks

CSRF is a common web application pattern where attackers attempt to “ride along” on an authenticated user’s session to trigger unintended actions. For background and examples of how these attacks work in practice, see:
