CVE-2025-1039 is a high-severity vulnerability affecting the Lenix Elementor Leads addon plugin for WordPress. This vulnerability allows stored cross-site scripting (XSS) via a URL form field in all versions up to and including 1.8.2, due to insufficient input sanitization and output escaping. Unauthenticated attackers may leverage this weakness to inject arbitrary web scripts into pages that will execute whenever a user accesses the compromised page.
The CVSS score for this vulnerability is 7.2, indicating a high level of severity. The attack vector is categorized as network-based with low complexity, meaning that an attacker does not require advanced skills to exploit this vulnerability. Additionally, it does not require any privileges or user interaction, which increases the risk of exploitation.
Risk to organizations includes potential unauthorized access to sensitive information and the ability for attackers to conduct further attacks through the compromised web pages. Organizations should prioritize patching immediately to mitigate this risk.
As of the last update, no known public exploit exists for this vulnerability, but the potential impact on users accessing affected sites remains a significant concern.
Vulnerability Details
The Lenix Elementor Leads addon plugin for WordPress is vulnerable to Stored Cross-Site Scripting via a URL form field in all versions up to, and including, 1.8.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation ('Cross-site Scripting').
The CVSS score is 7.2, indicating high severity, with a base severity rating of high from the vendor. The publication date for this vulnerability was February 20, 2025.
Technical Analysis
The root cause of this vulnerability is the insufficient sanitization of user input in the URL form field. Attackers can exploit this vulnerability by injecting malicious scripts into the URL, which will then be executed in the context of the victim's browser when they visit the affected page.
The attack vector is network-based, and the complexity is low, meaning that it can be easily executed without extensive knowledge. No privileges are required, and user interaction is not needed for successful exploitation.
The impact on confidentiality and integrity is low, but successful exploitation can lead to execution of arbitrary scripts, potentially affecting the availability of the web application.
Risk & Impact Analysis
Real-world deployment risk includes unauthorized manipulation of web pages, which could mislead users or extract sensitive information. The blast radius could be significant if multiple sites using this plugin are compromised, leading to widespread security concerns.
Organizations should also consider the potential regulatory implications of failing to address this vulnerability, as data breaches resulting from exploitation could lead to penalties.
Urgency for remediation is high due to the potential for exploitation without prior authentication. Organizations should address in priority patch cycle to mitigate risks.
