CVE-2025-7683 in LatestCheckins Plugin
Summary
by MITRE • 08/16/2025
The LatestCheckins plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1. This is due to missing or incorrect nonce validation on the 'LatestCheckins' page. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The CVE-2025-7683 vulnerability affects the LatestCheckins plugin for WordPress, representing a critical cross-site request forgery weakness that compromises the integrity of affected websites. This vulnerability exists in all versions of the plugin up to and including version 1, making it a persistent threat across the entire release history of this particular plugin. The flaw lies in the absence of proper nonce validation mechanisms within the plugin's administrative interface, specifically on the 'LatestCheckins' page where critical configuration settings are managed. Nonce validation serves as a cryptographic token that ensures requests originate from legitimate administrative users and prevents unauthorized modifications to plugin settings.
The technical exploitation of this vulnerability occurs through the manipulation of web requests that target the plugin's administrative functionality. An attacker can craft malicious requests that appear to come from legitimate administrative sessions, bypassing the standard authentication and authorization checks that should protect sensitive configuration modifications. This weakness allows unauthenticated attackers to inject malicious web scripts into the plugin's settings, potentially leading to persistent malicious code execution within the target WordPress environment. The vulnerability specifically targets the administrative interface where settings are modified, making it particularly dangerous as it enables attackers to alter core plugin configurations that may affect site functionality and security posture.
The operational impact of this vulnerability extends beyond simple configuration changes, as it provides attackers with the capability to establish persistent malicious presence within WordPress installations. When an administrator inadvertently clicks on a malicious link or visits a compromised webpage, the forged request can execute without proper validation, potentially allowing attackers to modify plugin settings, inject malicious code, or redirect users to malicious destinations. This type of attack can result in complete compromise of the affected WordPress site, enabling attackers to perform actions such as changing administrator credentials, installing backdoors, or using the compromised site as a launchpad for further attacks against other systems. The vulnerability's impact is amplified by the fact that it requires minimal user interaction beyond simply visiting a malicious webpage, making it particularly dangerous in phishing scenarios.
Mitigation strategies for CVE-2025-7683 should prioritize immediate plugin updates to versions that include proper nonce validation mechanisms, as this represents the most direct and effective solution to the vulnerability. Administrators should also implement additional security measures such as monitoring for unauthorized configuration changes, implementing web application firewalls that can detect and block suspicious requests, and conducting regular security audits of installed plugins. The vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications, and corresponds to ATT&CK technique T1190, which covers the exploitation of web application vulnerabilities to gain unauthorized access or modify system configurations. Organizations should also consider implementing principle of least privilege access controls and regularly updating all WordPress plugins to ensure protection against known vulnerabilities, as this particular weakness demonstrates how basic security mechanisms like nonce validation can be critical in preventing exploitation of administrative interfaces.
