Overview
CVE-2025-66098 details a Stored Cross-Site Scripting (XSS) vulnerability found in the Travelers’ Map WordPress plugin. This vulnerability allows an attacker to inject malicious scripts into the plugin’s data, which will then be executed in the browsers of other users who access the affected page. The vulnerability affects versions 2.3.2 and earlier of the Travelers’ Map plugin.
Technical Details
The vulnerability stems from the improper neutralization of input during web page generation. Specifically, the Travelers’ Map plugin fails to adequately sanitize user-supplied data before displaying it. This allows an attacker to inject arbitrary JavaScript code into fields or settings within the plugin. When other users, including administrators, view content generated by the plugin, the malicious script is executed in their browsers. This could potentially allow the attacker to steal sensitive information, deface the website, or perform other malicious actions on behalf of the user.
CVSS Analysis
Currently, both the severity and CVSS score for CVE-2025-66098 are listed as N/A. This might be because the score has not been fully calculated or published yet. However, based on the description of the vulnerability as a Stored XSS, it would likely receive a medium to high severity score if properly assessed. A Stored XSS can have significant impact.
Possible Impact
A successful Stored XSS attack through CVE-2025-66098 can have several serious consequences:
- Account Takeover: An attacker could potentially steal the cookies of administrative users, leading to account takeover.
- Data Theft: Sensitive data displayed or processed through the plugin could be compromised.
- Website Defacement: The attacker could modify the appearance or content of the website.
- Malware Distribution: The attacker could inject scripts that redirect users to malicious websites or download malware.
Mitigation and Patch Steps
The recommended course of action is to update the Travelers’ Map plugin to the latest version as soon as a patch is available. If an update is not yet available, consider the following temporary mitigations:
- Disable the Plugin: If possible, temporarily disable the Travelers’ Map plugin until a patch is released.
- Input Validation: Implement strict input validation and sanitization on all user-supplied data within the plugin’s settings if you have the ability to modify the plugin’s code. This is a short term fix and is not recommended unless you are a developer familiar with the plugin.
- Web Application Firewall (WAF): Consider using a Web Application Firewall (WAF) to filter out potentially malicious requests.
