The Ninja Forms plugin, a widely used contact form builder for WordPress, has been identified with a critical security flaw. This vulnerability, categorized as an Insecure Direct Object Reference (IDOR), could potentially expose sensitive form data to unauthorized individuals. If your WordPress website relies on Ninja Forms, understanding this risk and taking prompt action is absolutely essential to safeguard your users’ information.<\/p>\n
An IDOR vulnerability occurs when an application exposes a direct reference to an internal implementation object, such as a file, directory, or database record, without proper authorization checks. In the case of Ninja Forms, this oversight meant that unauthenticated attackers could potentially bypass security measures. If they obtained a leaked bearer token and could load any page containing the Submissions Table block, they would be able to read arbitrary form definitions and submission records. This could lead to the exposure of private user submissions, personal identifiable information, or other confidential business data collected through your forms.<\/p>\n
This specific security issue is officially identified as CVE-2025-11924. Its publication date was December 17, 2025. The core of the problem lies within the Ninja Forms plugin for WordPress. Security experts have rated this vulnerability as High severity, indicating a significant risk. Currently, the status of this CVE is “Analyzed,” meaning it has been thoroughly investigated and the technical details are well-understood within the security community.<\/p>\n
The Insecure Direct Object Reference (IDOR) vulnerability affects the Ninja Forms plugin across various versions. Specifically, all versions up to, and including, 3.13.2 are susceptible to this flaw. This means that if your WordPress installation is running Ninja Forms at version 3.13.2 or any earlier release, your website could be vulnerable to unauthorized data access. It’s vital to check your plugin version to assess your site’s exposure.<\/p>\n
As of the latest information, CVE-2025-11924 is in an “Analyzed” status. This classification signifies that the vulnerability has been fully researched, its mechanisms are understood, and its potential impact has been clearly defined. While the analysis is complete, site administrators are still responsible for applying the necessary fixes to mitigate the risk on their systems.<\/p>\n
The severity of CVE-2025-11924 is rated as High, with a CVSS score of 7.5. This high rating underscores the serious nature of the vulnerability. A high-severity flaw can lead to significant unauthorized access, data breaches, or other detrimental outcomes. For Ninja Forms, this means that an attacker, under specific conditions (a leaked bearer token and access to a page with the Submissions Table block), could bypass authentication to view sensitive form definitions and user-submitted data. The implications of such access could range from privacy violations to compliance issues, depending on the type of information collected via your forms.<\/p>\n
Fortunately, a robust solution is available to fully resolve this critical vulnerability. To effectively secure your WordPress website and protect the integrity of your form data, you must update your Ninja Forms plugin to version 3.13.3 or any subsequent release without delay.<\/p>\n
It’s important to note the history of this fix: an initial patch was released in version 3.13.1. However, this early attempt inadvertently introduced another security loophole. This new flaw allowed attackers to mint valid bearer tokens for any form ID, rendering the intended fix ineffective. The subsequent release, version 3.13.3, directly addresses both the original IDOR vulnerability and the unintended weakness introduced in 3.13.1, providing a comprehensive and secure resolution.<\/p>\n
To ensure your website’s security, we highly recommend implementing the following actions:<\/p>\n
By taking these steps, you can significantly reduce your website’s exposure to this and other potential threats.<\/p>\n
