CVE-2025-26552 is a high-severity vulnerability found in the badrHan Naver Syndication V2 plugin, which is susceptible to stored Cross-site Scripting (XSS) attacks. This vulnerability allows attackers to inject malicious scripts into web pages viewed by users, potentially compromising user data and application integrity. The CVSS score for this vulnerability is 7.1, indicating a high level of risk that organizations must take seriously.
Risk to organizations includes unauthorized data access, manipulation, and potential damage to reputation due to exploitation. The vulnerability affects all versions of the badrHan Naver Syndication V2 plugin up to version 0.8.3, and exploitation is possible through a network attack vector with low complexity, requiring no privileges but necessitating user interaction.
The vulnerability was published on February 13, 2025, and has not been confirmed to have a public exploit available. Organizations using the affected plugin should prioritize patching to mitigate the risk associated with this vulnerability.
Organizations should prioritize patching immediately to protect against potential exploitation. Given the nature of the vulnerability, it is critical to remain vigilant and implement security best practices in web application development.
Vulnerability Details
The vulnerability is characterized as an improper neutralization of input during web page generation, classified under CWE-79. The affected product is the badrHan Naver Syndication V2 plugin, which is vulnerable from an unspecified version to version 0.8.3. This vulnerability can lead to stored XSS, where malicious scripts are stored on the server and executed in the context of users' browsers.
The CVSS 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, indicating a network attack vector with low complexity, no privileges required, and user interaction needed. The impacts on confidentiality, integrity, and availability are all rated as low.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input, which allows malicious content to be stored and executed on the web application. The attack vector is network-based, meaning that an attacker can exploit this vulnerability without physical access to the system. The complexity of the attack is low, as it does not require any special conditions to be met, apart from the need for user interaction.
While no special privileges are required to exploit this vulnerability, user interaction is necessary, making it essential for users to be cautious of the content they interact with. The impacts on confidentiality are low, as the primary risk is related to the execution of scripts rather than direct access to sensitive data. Integrity and availability impacts are also rated as low.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-26552 is significant, particularly for organizations utilizing the affected plugin in their applications. Attackers may leverage this vulnerability to conduct phishing attacks, steal session cookies, or manipulate user inputs to execute unauthorized actions. The potential blast radius is considerable, as a successful attack can compromise not only the immediate users but also the broader community of users interacting with the affected application.
Given the CVSS score of 7.1, organizations should address this vulnerability in their priority patch cycle. Failure to do so could lead to severe consequences, including data breaches and loss of user trust. The urgency for remediation is underscored by the vulnerability's presence in widely used applications, making it a common target for attackers.
