The Welcart e-Commerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘name’ parameter in all versions up to, and including, 2.11.9 due to insufficient input sanitization and output escaping. This vulnerability allows unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
With a CVSS score of 7.2, this vulnerability is classified as high severity. The risk to organizations includes potential data theft, session hijacking, and other malicious activities that may arise from the exploitation of this flaw. Organizations should prioritize patching immediately.
Currently, there is no known public exploit for this vulnerability. However, the nature of cross-site scripting attacks makes it vital for organizations to remain vigilant and apply the necessary updates as soon as they are available.
The urgency of addressing this vulnerability is underscored by the potential for significant impact, especially in e-commerce environments where user trust and data integrity are paramount. Organizations must take proactive measures to mitigate risks associated with this vulnerability.
Vulnerability Details
The vulnerability in question affects the Welcart e-Commerce plugin for WordPress, specifically through the ‘name’ parameter. The lack of proper input sanitization and output escaping allows for stored cross-site scripting (XSS) attacks.
The CVSS score of 7.2 indicates a high severity level, highlighting the importance of addressing the issue promptly. The vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation (XSS).
The affected product is the Welcart e-Commerce plugin, and it is essential to note that all versions prior to 2.11.10 are vulnerable. The vulnerability was published on February 12, 2025, and the analysis of its impact remains ongoing.
Technical Analysis
The root cause of this vulnerability stems from the failure to adequately sanitize and escape user inputs. As a result, attackers can inject harmful scripts that execute in the context of the user’s browser, leading to various malicious outcomes.
The attack vector is network-based, allowing an attacker to exploit the vulnerability remotely without requiring any privileges or user interaction. The attack complexity is rated as low, making it accessible even to less skilled attackers.
In terms of impact, both confidentiality and integrity are affected with a low impact rating. However, there is no impact on availability, indicating that the plugin remains functional even when the vulnerability is exploited.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant, especially for e-commerce platforms that rely on user trust and data integrity. Attackers may leverage this vulnerability to launch XSS attacks, which can lead to unauthorized access to user sessions, data theft, and defacement of web pages.
The blast radius potential is high, as a successful attack could compromise the security of user accounts and sensitive information across potentially numerous websites utilizing the vulnerable plugin.
Given the CVSS score of 7.2, organizations should address this vulnerability in their priority patch cycle. The absence of known exploits does not diminish the urgency, as the nature of XSS vulnerabilities often leads to rapid exploitation once discovered.
