CVE-2025-23877 is a medium-severity vulnerability classified as a stored cross-site scripting (XSS) issue. This vulnerability allows attackers to inject malicious scripts into web pages generated by the Nitethemes Nite Shortcodes plugin for WordPress. Specifically, it affects Nite Shortcodes versions from n/a through 1.0. Given the nature of XSS vulnerabilities, they can lead to unauthorized actions on behalf of users and compromise sensitive information.
The CVSS score of 6.5 indicates a medium threat level, making it crucial for organizations utilizing this plugin to take immediate action. The vulnerability's exploitation could lead to significant consequences, particularly for web applications relying on user-generated content. Organizations should prioritize patching immediately.
As of now, there is no public exploit confirmed, and it is not listed in the Known Exploited Vulnerabilities (KEV) database. This presents a window of opportunity for organizations to apply necessary patches before any potential exploitation occurs.
Given the risk to organizations, the urgency for defenders is evident. Organizations using the affected versions of Nite Shortcodes should schedule remediation promptly to avoid falling victim to potential attacks.
Vulnerability Details
The vulnerability allows improper neutralization of input during web page generation, leading to stored XSS. This vulnerability's CVSS score of 6.5 categorizes it as medium severity. The affected product is the Nitethemes Nite Shortcodes plugin, with the issue affecting versions up to and including 1.0. The vulnerability was published on January 16, 2025.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user inputs during the web page generation process. Attackers can exploit this vulnerability by injecting malicious scripts that get stored on the server and are later executed in the browsers of unsuspecting users.
The attack vector for this vulnerability is network-based, and the complexity is low, meaning that an attacker does not need advanced skills to exploit it. It requires low privileges, and user interaction is necessary for the attack to succeed, as the victim must visit the compromised page.
The impacts of this vulnerability are classified as low for confidentiality, integrity, and availability. However, the implications of successful exploitation could lead to severe repercussions, including unauthorized access to user sessions and theft of sensitive data.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-23877 is significant. Stored XSS vulnerabilities can have a broad blast radius, potentially affecting all users interacting with the impacted web application. Organizations must understand the importance of addressing this type of vulnerability, not only to protect their users but also to maintain their reputation and trust.
Given the medium CVSS score, organizations should address this vulnerability in their priority patch cycle. The potential for exploitation is crucial, especially in environments where user-generated content is prevalent.
