CVE-2026-22194 is a critical cross-site request forgery (CSRF) vulnerability found in GestSup versions up to and including 3.2.60. This vulnerability allows attackers to manipulate logged-in users into making unauthorized requests, utilizing their privileges to perform actions such as creating privileged accounts. The risk of exploitation is significant, as it targets the administrative user creation endpoint.
With a CVSS score of 8.9, this vulnerability is classified as high severity. The attack vector is network-based, which means that it can be exploited remotely with low complexity and no privileges required. The potential impact includes high confidentiality, integrity, and availability effects, making it crucial for organizations to address this vulnerability promptly.
Organizations should prioritize patching immediately to prevent unauthorized access and potential abuse of user privileges. The urgency of remediation is underscored by the broad applicability of the vulnerability across all installations of the affected version.
As of now, there are no known exploits or public proofs of concept available, but the nature of CSRF vulnerabilities makes them attractive targets for attackers. Therefore, vigilance is necessary even in the absence of confirmed exploit activity.
Vulnerability Details
The official description of CVE-2026-22194 states: 'GestSup versions up to and including 3.2.60 contain a cross-site request forgery (CSRF) vulnerability where the application does not verify the authenticity of client requests. An attacker can induce a logged-in user to submit crafted requests that perform actions with the victim's privileges. This can be exploited to create privileged accounts by targeting the administrative user creation endpoint.'
The vulnerability is classified under CWE-352, which pertains to CSRF vulnerabilities. With a CVSS score of 8.9, the severity is rated as high. The attack vector is network-based, and the attack complexity is low. Importantly, no privileges are required for exploitation, and user interaction is passive.
The affected product is GestSup, specifically versions up to and including 3.2.60. The vulnerability was published on January 9, 2026, and has been analyzed for remediation efforts.
Technical Analysis
The root cause of this vulnerability lies in the absence of verification for the authenticity of client requests within the GestSup application. Attackers can exploit this weakness by crafting malicious requests that appear legitimate to the application, thus allowing them to perform actions on behalf of the user.
The attack vector is network-based, meaning that an attacker does not need physical access to the network to exploit this vulnerability. The attack complexity is low, indicating that the exploitation does not require advanced skills. No privileges are needed to execute the attack, and user interaction is passive, as the user may not even be aware they are being exploited.
The confidentiality, integrity, and availability impacts are all rated high, signifying that successful exploitation could lead to significant damage. Organizations using the affected versions must take immediate action to protect their environments.
Risk & Impact Analysis
Risk to organizations includes unauthorized actions taken on behalf of legitimate users, which can lead to the creation of privileged accounts and possible data breaches. The potential blast radius for organizations utilizing GestSup is significant, as the vulnerability affects all installations of the application up to version 3.2.60.
The urgency for organizations to address this vulnerability is high. Given its CVSS score of 8.9, it falls within the category of high severity. Organizations should address this vulnerability in their priority patch cycle to ensure the security of their systems.
