Vulnerability Details
The CVE-2026-0580 is a low-severity vulnerability affecting SourceCodester API Key Manager App version 1.0. The vulnerability's description indicates that a manipulation of the Import Key Handler component can lead to cross-site scripting, which allows attackers to execute scripts in the user's browser.
The vulnerability has a CVSS score of 2, classified as low severity, highlighting that while it poses a risk, it is not immediately critical. The affected component is identified as api_key_manager_app, and the vulnerability was published on January 5, 2026.
The weaknesses associated with this vulnerability include CWE-79 and CWE-94, which pertain to cross-site scripting and code injection respectively. The potential impacts include low integrity and no confidentiality or availability impacts.
Technical Analysis
The root cause of CVE-2026-0580 lies in the improper handling of user input within the Import Key Handler component, leading to cross-site scripting vulnerabilities. The attack vector is network-based, which means that an attacker can exploit this vulnerability remotely without needing physical access to the system.
The attack complexity is classified as low, indicating that attackers do not need specialized conditions to exploit it. Privileges required for exploitation are low as well; however, user interaction is necessary to trigger the exploit. The potential impacts on confidentiality are none, while the integrity impact is low, meaning that while data could be altered, it does not result in a complete breach.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access to user data, manipulation of web sessions, and the execution of malicious scripts. While the CVSS score indicates a low severity, the real-world risk should not be underestimated, especially if the API Key Manager App is used in sensitive environments.
The potential blast radius could be significant if multiple users are targeted, as the vulnerability can be exploited remotely. Organizations should address this vulnerability in their priority patch cycle to ensure that their systems remain secure.
Given the low urgency based on the CVSS score, organizations should schedule remediation during their regular maintenance cycles. However, they should remain vigilant regarding the application’s security posture and implement additional monitoring to detect any unusual behavior.
