CVE-2026-22913 is classified as a medium severity vulnerability with a CVSS score of 4.3. This vulnerability allows improper handling of a URL parameter, which may permit attackers to execute code in a user's browser after login. Consequently, this could lead to the extraction of sensitive data from the user.
The impact of this vulnerability is significant. Attackers may exploit this flaw to target users, potentially leading to unauthorized access to sensitive information. Given the nature of the vulnerability, the risk to organizations includes data compromise and loss of user trust.
The vulnerability was published on January 15, 2026, and has since been analyzed and classified as having a medium level of urgency. Organizations utilizing the affected product should prioritize patching to prevent potential exploitation.
Currently, there are no known exploits or public proofs of concept associated with this vulnerability, which suggests a lower immediate risk of exploitation. However, organizations should remain vigilant.
Vulnerability Details
The official description states that improper handling of a URL parameter may allow attackers to execute code in a user's browser after login, leading to the extraction of sensitive data. This flaw is categorized under CWE-79, which pertains to improper neutralization of input during web page generation ('Cross-site Scripting').
The CVSS score of 4.3 indicates a medium severity level, suggesting that while the vulnerability is not critical, it still presents a risk that requires attention. The attack vector is network-based, with low complexity and no privileges required for exploitation, necessitating user interaction.
Affected products include the Sick tdc-x401gl_firmware, specifically all versions prior to 1.5.0. The vulnerability has been published in various advisories but should be addressed promptly.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input in the URL. Attackers can exploit this flaw to inject malicious scripts that execute in the context of the user’s browser, especially after login. This creates a potential pathway for sensitive data extraction.
The attack vector is through the network, requiring an attacker to send a crafted URL to a user. The attack complexity is low, making it easier for less skilled attackers to exploit the vulnerability. Furthermore, the lack of required privileges means that any user interacting with the compromised URL could be affected.
User interaction is required to trigger the attack, as the user must click on the malicious link. The confidentiality impact is low, as the attacker may only be able to access data that the user can access. There is no integrity or availability impact associated with this vulnerability.
Risk & Impact Analysis
Real-world deployment risk is primarily associated with the potential for data breaches. Organizations utilizing the affected Sick tdc-x401gl_firmware should be particularly aware of the risk posed by this vulnerability, especially if sensitive data is handled through web applications.
The urgency for organizations to address this vulnerability is medium, as the CVSS score indicates a moderate risk level. Organizations should prioritize patching this vulnerability in their next patch cycle, as any delay could leave systems vulnerable to exploitation.
The potential blast radius includes any user of the affected system, which could lead to widespread data exposure if exploited. It is crucial for organizations to implement strong user education and awareness programs to mitigate risks associated with user interaction.
