CVE-2025-50021 represents a medium-severity vulnerability classified as a Cross-site Scripting (XSS) flaw. This vulnerability allows for improper neutralization of input during web page generation, specifically in the Better Random Redirect plugin developed by Robert Peake. The affected versions span from n/a through version 1.3.20, which poses a risk to users of this software.
The CVSS score for this vulnerability is 5.9, indicating a medium level of severity. Organizations need to prioritize addressing this vulnerability due to its potential impact. Risk to organizations includes unauthorized access to sensitive information via stored XSS attacks. Attackers may leverage this vulnerability to manipulate web content and execute scripts in the context of the user's session.
Currently, the vulnerability is classified as deferred, meaning it has not been actively exploited in the wild. However, organizations should remain vigilant and monitor for any signs of exploitation. Given its potential for misuse, organizations should prioritize patching immediately.
As of the latest information, there is no known public exploit available for this vulnerability, which further emphasizes the importance of timely remediation efforts.
Vulnerability Details
The official description of CVE-2025-50021 states that it allows for Stored XSS in the Better Random Redirect plugin. This vulnerability falls under CWE-79: Improper Neutralization of Input During Web Page Generation, which highlights the critical need for developers to sanitize input properly.
The vulnerability's metrics indicate an attack vector of NETWORK, a low attack complexity, and high privileges required for exploitation, meaning that an authenticated user would be necessary to leverage the flaw.
The impacts associated with this vulnerability include potential low confidentiality, integrity, and availability, suggesting that while the immediate risks may be medium, the implications could lead to more significant breaches if exploited.
Technical Analysis
The root cause of this vulnerability stems from the improper handling of user input, allowing attackers to inject malicious scripts that are subsequently executed in the context of users' browsers. This type of attack is particularly dangerous as it can lead to session hijacking, data theft, and other malicious activities.
The attack vector is primarily network-based, requiring low complexity to execute. Although high privileges are required to exploit the vulnerability, user interaction is necessary, which means that the success of such attacks depends on social engineering tactics to convince users to execute the payload.
The confidentiality, integrity, and availability impacts are all rated as low, indicating that while the immediate threat may not seem critical, the potential for exploitation exists and could lead to more severe consequences if exploited effectively.
Risk & Impact Analysis
Organizations using the Better Random Redirect plugin must understand the real-world implications of CVE-2025-50021. Given the nature of XSS vulnerabilities, attackers can potentially manipulate users into executing malicious scripts, leading to unauthorized actions on behalf of the user.
The potential blast radius is significant, especially for websites that handle sensitive user data. User trust can be severely eroded if such vulnerabilities are exploited, leading to long-term reputational damage.
The urgency for organizations to address this vulnerability is medium, as it is not classified as actively exploited now but has the potential for future exploitation. Organizations should schedule remediation as part of their vulnerability management program.
