CVE-2026-1439 is a Reflected Cross-Site Scripting (XSS) vulnerability found in the Graylog Web Interface console, specifically version 2.2.3. This flaw stems from insufficient sanitization and escaping of URL segments in HTML output, allowing attackers to inject and execute arbitrary JavaScript code via specially crafted URLs, particularly through the '/alerts/' endpoint. The vulnerability is rated Medium with a CVSS score of 6.1, indicating a network-based attack with low complexity, requiring user interaction. Successful exploitation could lead to script execution in the victim's browser and limited manipulation of their session context, resulting in partial loss of confidentiality and integrity. Currently, there is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal, aligning with the typical low engagement seen for most vulnerabilities.
