CVE-2026-22518 is a medium-severity vulnerability identified in the PencilWP X Addons for Elementor plugin. This vulnerability allows for improper neutralization of input during web page generation, specifically resulting in DOM-Based Cross-site Scripting (XSS). The affected versions include all versions up to and including 1.0.23.
The CVSS score for this vulnerability is 6.5, indicating a medium risk level. Organizations utilizing affected versions of the plugin should be aware of the potential for exploitation. The urgency for patching is classified as medium, emphasizing the need for timely remediation to prevent potential attacks.
Risk to organizations includes unauthorized access to sensitive user data and potential manipulation of web content. Attackers may leverage this vulnerability to execute malicious scripts in the context of the user's browser, leading to data theft or defacement of web applications.
Organizations should prioritize patching immediately by upgrading to the latest version of the plugin to mitigate risks associated with this vulnerability.
It is important to monitor for potential exploitation of this vulnerability, as XSS attacks are commonly exploited in the wild. Additionally, organizations should consider implementing web application firewalls to filter out malicious inputs.
Vulnerability Details
The vulnerability is classified as a Cross-site Scripting (XSS) vulnerability, specifically identified as CWE-79. The CVSS vector is CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L, indicating that it is network exploitable with low attack complexity and requires user interaction.
The vulnerability affects the PencilWP X Addons for Elementor plugin, with the specific versions impacted ranging from n/a through 1.0.23. The official publication date of this vulnerability is January 8, 2026.
Technical Analysis
The root cause of this vulnerability stems from improper input validation, which fails to adequately neutralize potentially harmful scripts before they are rendered in the web application. This oversight allows attackers to inject malicious scripts that are executed by unsuspecting users visiting affected pages.
Exploiting this vulnerability requires the attacker to have low privileges and necessitates user interaction, as the malicious script is executed in the user's browser context. The attack vector is primarily network-based, highlighting the importance of secure coding practices to prevent such vulnerabilities.
The attack complexity is classified as low, making it relatively easy for an attacker to exploit this vulnerability. The impacts on confidentiality, integrity, and availability are all rated as low, but the potential for XSS attacks can lead to significant risks if left unaddressed.
Risk & Impact Analysis
Real-world deployment risks associated with this vulnerability are critical. Organizations utilizing the affected versions of the PencilWP X Addons for Elementor plugin may face significant exposure to malicious attacks, leading to compromised user data and potential reputational harm.
The blast radius of this vulnerability is considerable, as it can affect any user who interacts with the compromised web application. The urgency assessment based on the CVSS score categorizes this vulnerability as medium, necessitating timely remediation efforts.
