CVE-2025-54024 details a medium-severity vulnerability within the WPAdverts plugin, which allows for improper neutralization of input during web page generation, resulting in a Cross-site Scripting (XSS) attack. The CVSS score for this vulnerability is 6.5, indicating a medium level of risk to organizations that utilize the affected plugin versions. The vulnerability allows attackers to leverage DOM-Based XSS, potentially compromising user data and website integrity.
The vulnerability affects all versions of WPAdverts up to and including version 2.2.5. Given the potential for exploitation through network vectors with low complexity and required user interaction, organizations should prioritize remediation efforts. This is especially important as the attack could lead to unauthorized actions within the context of the user's session.
As of now, there are no known exploits or public proof-of-concept (PoC) available for this vulnerability, but the potential impact remains significant. Organizations are urged to monitor for any updates or patches from the vendor and to implement necessary mitigation strategies.
Organizations should address this issue in their priority patch cycle to prevent potential exploitation. Regular security assessments and updates to plugins are essential in maintaining a secure web environment.
Vulnerability Details
The CVE-2025-54024 vulnerability is classified as a Cross-site Scripting (XSS) issue, specifically categorized under CWE-79. The CVSS 3.1 score is 6.5, indicating a medium severity level. The affected product is the WPAdverts plugin developed by Greg Winiarski, with the vulnerability affecting versions from n/a through 2.2.5. The official publication date of this vulnerability is July 16, 2025.
Technical Analysis
Root cause analysis indicates that the vulnerability arises from improper input validation during the web page generation process, allowing attackers to inject malicious scripts into the browser's DOM. The attack vector is network-based, requiring low complexity and low privileges. User interaction is necessary for successful exploitation, meaning that an attacker may need to trick a user into clicking a specially crafted link.
The impacts of this vulnerability include low confidentiality, integrity, and availability. An attacker may gain access to session cookies, which could lead to unauthorized actions performed in the context of the affected user.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to user data and disruption of service. Given the nature of XSS vulnerabilities, the blast radius can be significant, especially if the affected plugin is widely used. The urgency for organizations to address this vulnerability is medium, as the CVSS score indicates a moderate risk, and the lack of known exploits does not diminish the need for proactive measures.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerability affects all versions of WPAdverts prior to version 2.2.5. Organizations should ensure that they are using the latest version of the plugin to mitigate this risk.
Mitigation & Remediation
Organizations should prioritize patching the WPAdverts plugin to the latest version to address this vulnerability. If an immediate update is not possible, consider implementing web application firewalls (WAFs) to filter out malicious requests and monitor user interactions for suspicious behavior. Regular security audits and scans should be conducted to identify and remediate vulnerabilities.
Detection Guidance
To detect potential exploitation attempts of this vulnerability, organizations should monitor logs for unusual activity associated with user sessions. Pay attention to any unexpected scripts being executed or injected into web pages. Implementing behavioral analysis can help identify anomalies in user interactions.
