CVE-2025-4189 in Audio Comments Plugin
Summary
by MITRE • 05/17/2025
The Audio Comments Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.4. This is due to missing or incorrect nonce validation on the 'audio-comments/audior-settings.php' 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 Audio Comments Plugin for WordPress represents a significant security vulnerability classified as CVE-2025-4189, affecting all versions up to and including 1.0.4. This vulnerability manifests as a cross-site request forgery flaw that fundamentally undermines the plugin's security posture. The issue stems from inadequate nonce validation mechanisms within the plugin's administrative interface, specifically on the 'audio-comments/audior-settings.php' page where critical configuration parameters can be modified without proper authentication verification. The absence of proper nonce implementation creates a dangerous attack vector that can be exploited by malicious actors to manipulate plugin settings and potentially compromise the entire WordPress installation.
The technical exploitation of this vulnerability occurs through the manipulation of HTTP requests that target the plugin's settings page. Attackers can craft malicious requests that appear to originate from legitimate administrative sessions, leveraging the lack of proper nonce validation to execute unauthorized modifications. This flaw operates under the CWE-352 category of Cross-Site Request Forgery, which is a well-documented security weakness in web applications where the attacker can trick authenticated users into performing unintended actions. The vulnerability specifically aligns with ATT&CK technique T1213.002 which involves obtaining credentials through manipulation of web applications, and T1071.004 which covers application layer protocol manipulation.
The operational impact of this vulnerability extends beyond simple configuration changes, as it provides attackers with the potential to inject malicious web scripts into the plugin's administrative interface. This capability allows for persistent malicious activities including the execution of arbitrary code, data exfiltration, and potential privilege escalation within the WordPress environment. The fact that this affects unauthenticated attackers means that no prior access credentials are required to exploit the vulnerability, making it particularly dangerous. An attacker only needs to convince a site administrator to click on a malicious link or visit a compromised webpage that triggers the forged request. The consequences can range from complete site compromise to unauthorized data manipulation and potential backdoor establishment.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. The most critical immediate action is to update the Audio Comments Plugin to version 1.0.5 or later, where the nonce validation has been properly implemented. Administrators should also implement additional security measures including regular security audits of installed plugins, monitoring for unauthorized configuration changes, and maintaining up-to-date security frameworks. Network-level protections such as web application firewalls can provide additional defense-in-depth, while regular security scanning should be implemented to detect similar vulnerabilities in other installed components. The vulnerability serves as a reminder of the critical importance of proper input validation and authentication mechanisms in web applications, particularly within content management systems where plugins often have elevated privileges and access to sensitive system functions.
