The Yaffa v2.0.0 application is vulnerable to Cross Site Scripting (XSS). This vulnerability allows attackers to inject malicious JavaScript into the "Add Account Group" function on the account-group page, enabling execution of arbitrary scripts in the context of users who view the affected page. The severity level of this vulnerability is classified as medium, with a CVSS score of 6.1, indicating that while it poses a risk, it is not the most critical threat.
Risk to organizations includes potential unauthorized access to sensitive information and manipulation of user interactions on the affected page. The exploit can be executed remotely, requiring only user interaction, which increases the likelihood of successful exploitation.
Organizations should prioritize patching immediately. Given the nature of XSS vulnerabilities, a successful attack could lead to significant data breaches, making it imperative to address this risk promptly.
As of now, there are no known exploits or public proofs of concept for this vulnerability, but the potential for exploitation remains due to the application's functionality that allows for script injection.
Vulnerability Details
According to the official CVE description, the vulnerability in Yaffa allows for Cross Site Scripting (XSS), specifically through the "Add Account Group" function. The CVSS score of 6.1 categorizes it as medium severity, highlighting the necessity for organizations to take timely action.
The vulnerability is associated with CWE-94, which pertains to code injection. The affected product is Yaffa, version 2.0.0, from the vendor Kantorge. The vulnerability was published on April 7, 2026.
Technical Analysis
The root cause of this vulnerability is improper input validation, which allows attackers to insert malicious JavaScript code into the application. The attack vector is network-based, requiring user interaction to execute the injected script. The attack complexity is low, and no privileges are required for an attacker to exploit this vulnerability.
User interaction is required for successful exploitation, as users must visit the affected page where the malicious script is embedded. The confidentiality and integrity impacts are classified as low, meaning there is a risk of unauthorized data exposure and modification, while availability is not impacted.
Risk & Impact Analysis
The deployment of Yaffa v2.0.0 exposes organizations to significant risks, including potential data theft and unauthorized access to user accounts. The nature of XSS attacks means that the blast radius can be extensive, affecting all users who interact with the compromised page.
Given the medium CVSS score and the absence of any known exploitation details, organizations should assess their usage of Yaffa and prioritize remediation efforts within their patching cycles to mitigate risks associated with this vulnerability.
