CVE-2025-23631 is classified as a high-severity vulnerability due to its CVSS score of 7.1. This vulnerability allows improper neutralization of input during web page generation, specifically resulting in reflected Cross-site Scripting (XSS). This issue affects the Sarah Lewis Content Planner plugin, with versions prior to or equal to 1.0 being vulnerable. Given the nature of XSS vulnerabilities, organizations using this plugin are at risk of having attackers potentially execute scripts in the context of the victim's browser.
Risk to organizations includes unauthorized access to sensitive data, session hijacking, and the potential for malicious redirects. The vulnerability has been categorized as deferred, indicating that while it is acknowledged, it may not have immediate remediation available. Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability.
Currently, there are no known exploits for this vulnerability, and it has not been included in the Known Exploited Vulnerability (KEV) database. However, the potential for exploitation remains, especially given the high severity of the CVSS score. Organizations that utilize the Sarah Lewis Content Planner should track updates closely and prepare to implement patches as soon as they become available.
Given the nature of web application vulnerabilities, organizations must remain vigilant. Continuous monitoring and assessment of the security posture surrounding the use of such plugins is vital to maintaining overall security.
Vulnerability Details
The CVE-2025-23631 vulnerability is a result of improper neutralization of user input during the generation of web pages, allowing for reflected XSS attacks. This vulnerability is classified under CWE-79, which pertains to improper neutralization of input for web page generation. The issue affects the Sarah Lewis Content Planner plugin, specifically versions n/a through 1.0.
The CVSS v3.1 score for this vulnerability is 7.1, indicating a high severity level. The attack vector is network-based, with a low attack complexity. No user privileges are required to exploit this vulnerability, but user interaction is necessary for the attack to be successful. The impacts on confidentiality, integrity, and availability are all rated as low.
Technical Analysis
The root cause of CVE-2025-23631 lies in the inadequate sanitization of user inputs in the web application. Attackers may leverage this weakness to inject malicious scripts into web pages viewed by other users. As a result, the exploitation of this vulnerability can lead to unauthorized access to user sessions, sensitive data exposure, and other malicious activities.
The attack vector is primarily network-based, indicating that an attacker does not need physical access to the device but can exploit the vulnerability remotely. The attack complexity is classified as low, meaning it can be executed with minimal technical skill. No special privileges are required to exploit this vulnerability, although user interaction is necessary to trigger the execution of the malicious script.
Confidentiality, integrity, and availability impacts are all rated as low, indicating that while the threats are significant, the immediate effects may not lead to catastrophic failures. However, organizations must still take the potential risks seriously.
Risk & Impact Analysis
The real-world deployment risk concerning CVE-2025-23631 is significant due to the nature of XSS vulnerabilities. Attackers can exploit this flaw to execute scripts in the context of the victim's browser, leading to potential data breaches, unauthorized access, and other forms of exploitation. Organizations utilizing the Sarah Lewis Content Planner should be aware of the implications, especially in environments handling sensitive information.
The blast radius for this vulnerability can be considerable, as multiple users interacting with the affected web application could be impacted simultaneously. Furthermore, attackers can leverage XSS vulnerabilities to perform further attacks, such as phishing or credential harvesting, increasing the overall risk profile for organizations.
Given the CVSS score of 7.1, organizations should address this vulnerability in their priority patch cycle. The urgency for remediation is high; organizations must implement patches as soon as they become available to mitigate potential exploitation.
