CVE-2026-5301: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in CoolerControl coolercontrol-ui
CVE-2026-5301 is a stored cross-site scripting (XSS) vulnerability in the log viewer component of CoolerControl's coolercontrol-ui versions prior to 4. 0. 0. This flaw allows unauthenticated attackers to inject malicious JavaScript into log entries, which can then execute in the context of the service. Exploitation could lead to service takeover through script execution. The vulnerability has a high severity rating with a CVSS score of 7. 6. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability involves improper neutralization of input during web page generation (CWE-79) in the coolercontrol-ui log viewer prior to version 4.0.0. Specifically, stored XSS occurs when malicious JavaScript is injected into log entries, which are then rendered without proper sanitization, allowing execution of attacker-controlled scripts. The vulnerability is remotely exploitable without authentication and requires user interaction (UI:R). The impact includes partial confidentiality loss, high integrity impact, and low availability impact as per the CVSS vector.
Potential Impact
An attacker can inject malicious JavaScript into log entries viewed by the service, potentially leading to service takeover or unauthorized actions performed in the context of the affected application. The confidentiality impact is limited, but integrity is highly affected due to script execution capabilities. Availability impact is low. No known exploits have been reported so far.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the log viewer interface to trusted users only and consider implementing web application firewall (WAF) rules to detect and block suspicious input patterns related to script injection. Monitor vendor channels for updates regarding patches or official mitigations.
