CVE-2026-6107 is a cross-site scripting (XSS) vulnerability discovered in 1Panel-dev MaxKB versions 2.6.0 to 2.8.0. This flaw stems from improper handling of the 'Name' argument within the chatheadersmiddleware.py file, enabling remote attackers to inject malicious scripts. The vulnerability is rated as LOW severity and can be resolved by upgrading to version 2.8.0.
The XSS vulnerability in 1Panel-dev MaxKB allows an attacker to inject arbitrary JavaScript code into web pages viewed by other users. This can lead to various malicious actions, including stealing user cookies, redirecting users to phishing sites, or defacing the website. The impact is amplified if the 1Panel-dev MaxKB instance is used in a multi-tenant environment, as a single successful attack could compromise multiple users. While the CVSS score is LOW, the ease of exploitation and potential for session hijacking make this a significant concern, particularly for environments with sensitive data or critical functionality.
CVE-2026-6107 was disclosed on 2026-04-12. Currently, there are no publicly available proof-of-concept exploits. The vendor responded promptly and released a patch, indicating a proactive approach to security. The vulnerability is not listed on the CISA KEV catalog at the time of this writing, but its LOW severity and lack of public exploits suggest a low probability of immediate widespread exploitation.
Organizations using 1Panel-dev MaxKB in versions 2.6.0 through 2.8.0 are at risk. This includes users who rely on 1Panel-dev MaxKB for chat functionality and those who have not implemented robust input validation practices. Shared hosting environments utilizing 1Panel-dev MaxKB are particularly vulnerable due to the potential for cross-tenant exploitation.

The primary mitigation for CVE-2026-6107 is to upgrade 1Panel-dev MaxKB to version 2.8.0, which includes the necessary patch (026a2d623e2aa5efa67c4834651e79d5d7cab1da). If an immediate upgrade is not feasible, consider implementing input validation and output encoding on the Name parameter within the chatheadersmiddleware.py file. Web application firewalls (WAFs) configured to detect and block XSS payloads can also provide a temporary layer of protection. After upgrading, confirm the fix by attempting to inject a simple JavaScript payload (e.g., <script>alert('XSS')</script>) through the affected parameter and verifying that it is properly sanitized.
