Attack Vectors

CVE-2024-25931 is a Medium severity Cross-Site Request Forgery (CSRF) vulnerability affecting the Heureka WordPress plugin (slug: heureka) in all versions up to and including 1.0.8 (CVSS 4.3).

This type of attack relies on user interaction: an unauthenticated attacker would need to trick a site administrator (or another privileged user) into clicking a link or visiting a malicious page while they are logged into WordPress. If successful, the attacker may be able to make the admin’s browser submit a request to your site “as if” the admin intended it.

Security Weakness

The issue is caused by missing or incorrect nonce validation in an unknown function within the Heureka plugin. In WordPress, nonces are commonly used to confirm that sensitive actions (like settings changes) were intentionally initiated by an authorized user.

When nonce checks are absent or implemented incorrectly, a third party can potentially cause administrative actions to be performed without the administrator’s informed consent, as long as the administrator is authenticated at the time.

Technical or Business Impacts

According to the public advisory, the specific action an attacker could trigger is unknown, and therefore the direct impact is also unknown. However, CSRF weaknesses commonly translate into unauthorized changes made through an admin’s session—such as configuration adjustments or workflow disruptions—depending on what the vulnerable function controls.

From a business-risk perspective, even “limited” unauthorized changes can create operational and reputational exposure: unexpected site behavior, time spent on investigation and recovery, potential compliance concerns if site configurations are altered, and loss of confidence from customers or partners if marketing or ecommerce processes are impacted.

Remediation: Update the Heureka plugin to version 1.1.0 or newer (patched). Reference: Wordfence advisory. CVE record: CVE-2024-25931.
