CVE-2026-39107: n/a
CVE-2026-39107 is a Cross Site Scripting (XSS) vulnerability in the Kimi AI v1.0 web interface's 'Preview' feature. The application does not properly sanitize or encode HTML/JavaScript payloads generated by the AI model. When users switch to the 'Preview' tab, malicious payloads can be executed in their browser sessions, leading to arbitrary JavaScript execution. This vulnerability has a medium severity rating with a CVSS score of 6.3. No affected versions or patches are currently specified.
AI Analysis
Technical Summary
This vulnerability involves improper sanitization or encoding of AI-generated HTML/JavaScript content in the Kimi AI v1.0 web interface's 'Preview' feature. When a user views AI-generated code in the 'Preview' tab, malicious scripts embedded in the payload are executed directly in the victim's browser DOM, resulting in Cross Site Scripting (CWE-79). The CVSS 3.1 base score is 6.3, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and low impact on confidentiality, integrity, and availability. No official remediation or patch information is available at this time.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of the victim's browser session when viewing the 'Preview' tab. This can lead to session hijacking, information disclosure, or other client-side impacts. The vulnerability affects confidentiality, integrity, and availability at a low level. There are no known exploits in the wild currently.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution when interacting with AI-generated content in the 'Preview' feature. Consider restricting access to the 'Preview' tab or implementing additional input sanitization and output encoding controls if possible.
