CVE-2025-22594 is a high-severity vulnerability affecting the hccoder Better User Shortcodes plugin, specifically allowing for reflected Cross-site Scripting (XSS) attacks. This vulnerability allows attackers to inject malicious scripts into webpages viewed by users, exploiting the way user input is processed during web page generation. The severity level of 7.1 indicates a significant risk that organizations must address to prevent exploitation.
The vulnerability has been classified as CWE-79, which pertains to improper neutralization of input during web page generation. Given the nature of XSS vulnerabilities, the potential impact can be severe, allowing attackers to obtain sensitive information or perform actions on behalf of users without their consent.
This vulnerability has been publicly disclosed on January 9, 2025, and is applicable to all versions of the Better User Shortcodes plugin up to and including version 1.0. Organizations utilizing this plugin should evaluate their exposure and take immediate action.
Given the high CVSS score, organizations should prioritize patching immediately. Current intelligence indicates that there is no known exploit available for this vulnerability, but the potential for exploitation remains significant.
Vulnerability Details
The vulnerability allows for reflected XSS due to improper neutralization of user input. The CVSS 3.1 score of 7.1 categorizes this as high severity, indicating a potential for significant impact on confidentiality, integrity, and availability. The affected product, Better User Shortcodes, is an essential plugin for WordPress users, making its security paramount.
Organizations must understand that the vulnerability exists in versions of Better User Shortcodes from n/a through 1.0. The attack vector is network-based, requiring low complexity for exploitation. User interaction is needed, as an attacker must trick a victim into clicking a malicious link.
Technical Analysis
The root cause of this vulnerability lies in how the Better User Shortcodes plugin processes and sanitizes user input. The failure to adequately neutralize input during web page generation allows attackers to inject arbitrary scripts. The attack complexity is rated as low, meaning that an attacker doesn’t require extensive knowledge or resources to exploit this vulnerability.
To exploit this vulnerability, attackers primarily need to lure users into clicking on crafted links that lead to the vulnerable application. Once the user is tricked into interacting, the injected script can execute in the context of the user's session. This can lead to unauthorized actions, such as data theft or user impersonation.
Risk & Impact Analysis
Risk to organizations includes the potential loss of sensitive user data, unauthorized access to accounts, and a compromised administrative control. The blast radius for this vulnerability can be significant, particularly for organizations with a large user base relying on the Better User Shortcodes plugin.
Organizations should assess their deployment of the Better User Shortcodes plugin and prioritize this vulnerability in their patch management processes. Given that this vulnerability has a high CVSS score, it should be addressed in the immediate patch cycle to mitigate potential risks.
With an EPSS score of 0.00112, this vulnerability is in the lower percentile of exposure risk, but the implications of an exploit remain high. Organizations are advised to monitor their environments closely for signs of exploitation.
