CVE-2026-14950Network attack vector

Persistent web access via expired session identifiers

Published Aug 20, 2026 · Updated Aug 20, 2026

Insufficient session expiration in Frauscher FDS102 2.1.0 through 2.13.3 allows remote attackers to retain web-interface access. Flawed session-expiration logic continues accepting a valid session identifier after the associated session should have expired. Exploitation requires a previously valid session identifier; reuse preserves that session's web privileges beyond the configured lifetime.
