CVE-2026-14948Network attack vector

Administrative session hijack via logged session IDs

Published Aug 20, 2026 · Updated Aug 20, 2026

Sensitive information exposure in Frauscher FDS102 2.13.0 through 2.13.3 lets remote authenticated users hijack admin sessions via error-log archives. The Frauscher Diagnostic System FDS102 writes live plaintext session identifiers for authenticated web users into error logs and exposes those logs through downloadable archive files. Low-privileged access is enough, but an administrator session must already be active and its identifier still valid; the flaw enables session takeover without disclosing the administrator password itself.
