CVE-2025-8308Network attack vector

Script execution via unneutralized HTTP header

Published Feb 18, 2026 · Updated Feb 18, 2026

Cross-site scripting in Key Yazılım INFOREX through 18022026 allows remote attackers to inject script via crafted HTTP headers. The CNA does not identify the affected endpoint or header, or explain how the header value enters generated page content without context-appropriate encoding. Exploitation is unauthenticated over a network but requires a user to load the affected response, enabling script execution in that user's browser with limited confidentiality, integrity, and availability impact.
