  "description": "Thales published two CVEs on Oct 30 2026 for Sentinel Keys Server on Windows, the license server used with Sentinel Keys software protection. CVE-2026-78403 (CVSS 4.0 9.3 critical) is a stack-based buffer overflow with missing authorization: the server doesn't check the length of the first field in an HTTP request, so an unauthenticated remote attacker can send a crafted request that may lead to code execution as NT AUTHORITY\\SYSTEM. CVE-2026-78402 (CVSS 4.0 7.3 high) is a similar unchecked first field in local input messages that allows local privilege escalation to SYSTEM. Both affect versions lower than 1.3.8.0. No exploitation has been reported so far.",
