CVE-2025-13144

ContentStudio <= 1.3.7 - Cross-Site Request Forgery to Settings Update

Published Dec 5, 2025 CVSS 3.1 · 4.3 Medium EPSS < 1% KEV · Not listed

Description

The ContentStudio plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3.7. This is due to missing or insufficient nonce validation on the add_cstu_settings function. This makes it possible for unauthenticated attackers to modify plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Analysis

Technical impact

The vulnerability occurs because the ContentStudio plugin for WordPress fails to validate a nonce in its add_cstu_settings function, enabling Cross‑Site Request Forgery. Unauthenticated attackers can forge a request that a site administrator might click, thereby altering plugin configuration without needing to log in. The weakness is identified as CWE‑352.

Affected Systems

The issue affects the ContentStudio plugin for WordPress for all versions up to and including version 1.3.7. Users running these or older releases are vulnerable. No other products are listed as impacted.

Risk and Exploitability

The CVSS score of 4.3 indicates a medium severity and the EPSS score of less than 1% suggests a low probability of exploitation at the time of assessment. The vulnerability is not listed in the CISA KEV catalog, implying no known widespread exploitation. Attackers can leverage this flaw by crafting a forged link that an administrator might click, thus exploiting the lack of nonce validation.

OpenCVE Recommended Actions

Update the ContentStudio plugin to a version newer than 1.3.7, where nonce validation is implemented for settings updates.
If an immediate update is not possible, deploy a web application firewall rule to block or monitor HTTP requests to the settings endpoint that lack a valid nonce token.
Implement strict administrative access controls, limiting who can view and change plugin settings, and regularly audit the settings for unexpected changes.
