CVE-2025-23596 is a high-severity vulnerability classified as a Cross-site Scripting (XSS) issue. This vulnerability allows attackers to exploit the Notifikácie.sk WordPress plugin to execute reflected XSS attacks, potentially compromising the integrity of the web application and affecting user data.
With a CVSS score of 7.1, this vulnerability poses a significant threat, particularly due to its ability to be exploited over the network and its low attack complexity. Organizations using versions of Notifikácie.sk prior to 1.0 should be particularly vigilant.
The risk to organizations includes potential unauthorized access to sensitive information and the ability to manipulate user sessions. Given the nature of XSS attacks, the urgency for defenders is high, and they should prioritize patching immediately.
As of now, no known public exploits exist for this vulnerability, and it has not been included in the KEV catalog, but organizations should not underestimate the risk and should take preemptive measures to secure their systems.
Vulnerability Details
The official description of CVE-2025-23596 states that it involves improper neutralization of input during web page generation, leading to reflected XSS vulnerabilities in the Notifikácie.sk plugin. The plugin is used within WordPress environments, and this vulnerability can affect versions from n/a to 1.0.
The CVSS 3.1 vector string for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L, reflecting a network attack vector, low attack complexity, no privileges required, and required user interaction. The overall impact on confidentiality, integrity, and availability is rated as low.
CWE-79 (Improper Neutralization of Input During Web Page Generation) is the relevant weakness associated with this vulnerability, highlighting how input handling flaws can lead to severe security issues.
Technical Analysis
The root cause of this vulnerability lies in the inadequate sanitization of user inputs within the Notifikácie.sk plugin. Attackers may leverage this flaw to inject malicious scripts into web pages that are then executed in the browsers of unsuspecting users.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely. The attack complexity is low, as it requires no special privileges and necessitates user interaction, making it easier to execute.
The confidentiality, integrity, and availability impacts are all rated as low, but the potential for data theft or session hijacking should not be underestimated. Therefore, organizations must be proactive in mitigating this risk.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-23596 is significant, especially for organizations relying on the Notifikácie.sk plugin. If exploited, attackers could gain unauthorized access to user data, manipulate session information, and potentially compromise the integrity of the entire web application.
Organizations should consider the blast radius of such an attack, as it could affect all users of the vulnerable plugin, leading to widespread data breaches and loss of user trust.
Given the CVSS score of 7.1, the urgency for remediation is high. Organizations should address this vulnerability in their priority patch cycle to safeguard their systems against potential exploitation.
