CVE-2025-23438 is a high-severity reflected cross-site scripting (XSS) vulnerability affecting the WP PT-Viewer plugin for WordPress. This vulnerability allows attackers to inject arbitrary scripts into web pages viewed by users, potentially leading to unauthorized actions and data theft. The CVSS score associated with this vulnerability is 7.1, indicating a significant risk to organizations utilizing this plugin.
The vulnerability affects all versions of WP PT-Viewer up to and including version 2.0.2. Given its nature, the flaw can be exploited remotely over the network, with low attack complexity and no privileges required. User interaction is necessary, as the victim must click on a malicious link for the attack to succeed. Organizations using this plugin should prioritize patching to mitigate potential risks.
Risk to organizations includes exposure to XSS attacks, which can lead to session hijacking, defacement, or redirection to malicious sites. As such, organizations should address this vulnerability immediately to protect their users and maintain the integrity of their systems.
As of the latest updates, there is no public exploit confirmed for this vulnerability, but its potential impact necessitates a proactive stance in vulnerability management.
Vulnerability Details
The CVE-2025-23438 vulnerability arises from improper neutralization of input during web page generation, which allows for reflected XSS attacks. The issue has been classified under CWE-79.
The vulnerability was published on January 16, 2025, and the affected product is WP PT-Viewer, specifically versions from n/a through <= 2.0.2. The attack vector is determined to be network-based, and the associated CVSS vector string is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L.
Technical Analysis
The root cause of CVE-2025-23438 lies in the failure to properly sanitize user inputs before outputting them in web pages. This flaw permits attackers to craft malicious links that, when clicked by unsuspecting users, execute arbitrary scripts in their browsers. The attack complexity is low, and attackers do not require any privileges to exploit this vulnerability.
User interaction is necessary for exploitation, as the victim must click on a crafted link. If successful, the attacker can manipulate user sessions, steal sensitive information, or redirect users to malicious sites. The confidentiality, integrity, and availability impacts are assessed as low.
Risk & Impact Analysis
Organizations using WP PT-Viewer are at significant risk due to the potential for successful XSS attacks. The vulnerability's ability to compromise user sessions can lead to unauthorized access and data breaches, impacting user trust and organizational reputation. Given that the attack vector is network-based and requires user interaction, organizations must ensure their users are aware of the risks associated with clicking unknown links.
With a CVSS score of 7.1, this vulnerability falls into the high-severity category, demanding immediate attention from security teams. The EPSS score of 0.00346 places it in the 0.57th percentile, indicating a lower likelihood of exploitation compared to other vulnerabilities, but the potential impact remains substantial.
