CVE-2025-23695 is classified as a high-severity reflected Cross-site Scripting (XSS) vulnerability affecting the CtyGrid Hyp3rL0cal Search plugin. It allows attackers to inject malicious scripts into web pages viewed by other users. The CVSS score of 7.1 underscores the potential impact of this vulnerability, which can lead to unauthorized access and data exposure.
The vulnerability was disclosed on January 22, 2025, and it affects all versions of CtyGrid Hyp3rL0cal Search up to and including 0.1.1.1. Given the nature of XSS attacks, the risk to organizations includes the potential for data theft, session hijacking, and defacement of web applications.
Currently, there are no known exploits in the wild, but the presence of a significant vulnerability like this necessitates immediate attention from security teams. Organizations that utilize this plugin should prioritize patching to protect against possible exploitation.
Given that this vulnerability is classified as deferred, it is crucial for organizations to stay updated with the latest security patches and updates from the vendor.
Vulnerability Details
The vulnerability allows for improper neutralization of input during web page generation, specifically enabling reflected XSS. According to the CVSS, the attack vector is classified as NETWORK, with low attack complexity and no required privileges, but it does require user interaction. The confidentiality, integrity, and availability impacts are all rated as low.
The CVE was published with a CWE classification of CWE-79, indicating that it is related to improper neutralization of input during web page generation. This vulnerability could allow attackers to execute arbitrary JavaScript in the context of the user's browser.
Technical Analysis
The root cause of this vulnerability is the failure to properly sanitize user input before displaying it on the web page. Attackers may leverage this oversight to manipulate the site's behavior and execute scripts that can hijack user sessions or perform unauthorized actions.
The attack vector is through the network where a user might be tricked into clicking on a malicious link that leads to the vulnerable site. The attack complexity is considered low, as it does not require sophisticated techniques to exploit, and no privileges are needed to initiate the attack.
User interaction is required, meaning the user must visit a malicious link or interact with a crafted element on the page for the attack to succeed. The confidentiality, integrity, and availability impacts are all assessed to be low, meaning the overall potential damage from an attack is limited but still significant.
Risk & Impact Analysis
Risk to organizations includes data exposure and potential unauthorized access to user accounts. The blast radius is contingent on how widely the vulnerable plugin is deployed across applications and the ability of attackers to craft convincing phishing attempts to entice users into clicking malicious links.
Despite the absence of active exploitation evidence, organizations should treat this vulnerability with urgency and address it in their patch management cycles. The CVSS score of 7.1 indicates a high potential impact, warranting immediate remediation efforts to mitigate risks.
Organizations should prioritize patching immediately. Regular vulnerability assessments and real-time monitoring for exploits should be part of a comprehensive security strategy.
