CVE-2026-28126 is a high-severity vulnerability classified as Cross-site Scripting (XSS) affecting sizam RH Frontend Publishing Pro. This vulnerability allows improper neutralization of input during web page generation, potentially enabling attackers to execute arbitrary scripts in the context of a user's session. The CVSS score for this vulnerability is 7.1, indicating a significant threat that organizations must address to prevent exploitation.
The vulnerability has been assigned a CVSS 3.1 score with a vector string of CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L. This indicates that it can be exploited over the network with low complexity and does not require elevated privileges, but does require user interaction.
Risk to organizations includes potential unauthorized access to sensitive user data, manipulation of website content, and the ability to perform actions on behalf of users. The urgency for defenders is high, as the vulnerability affects all versions of the software prior to 4.3.4.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. Without remediation, they risk exposing users to malicious scripts that could compromise personal and sensitive information.
Vulnerability Details
The vulnerability allows for reflected XSS, where an attacker can inject malicious scripts that are executed in the user's browser when visiting a compromised page. This specific vulnerability affects sizam RH Frontend Publishing Pro, with the issue reported to impact versions n/a through < 4.3.4.
The official CWE classification for this vulnerability is CWE-79, which pertains to improper neutralization of input during web page generation. Organizations are encouraged to review their usage of the affected software and implement appropriate patches.
Technical Analysis
The root cause of this vulnerability lies in the inadequate sanitization of user inputs, allowing attackers to manipulate web page content. The attack vector is network-based, meaning it can be exploited by attackers who can send crafted requests to the affected system.
The attack complexity is low, as no special conditions are required for exploitation. Additionally, the vulnerability requires no privileges but does require user interaction, as the victim must be tricked into clicking on a malicious link.
The potential impacts of this vulnerability include low confidentiality, integrity, and availability impacts. Attackers may leverage this vulnerability to gain unauthorized access to user sessions and execute arbitrary scripts in their context.
Risk & Impact Analysis
The risk to organizations includes not only the direct impact on users but also potential reputational damage and loss of trust. The blast radius can be significant, as a successful exploit may allow attackers to manipulate website functionalities or access sensitive user information.
Given the CVSS score of 7.1, organizations should address this vulnerability in their priority patch cycle. The urgency for remediation is high, especially considering the potential for widespread exploitation if left unpatched.
