CVE-2025-8696Network attack vector

Unauthenticated process crash via oversized UI input

Published Sep 10, 2025 · Updated Nov 4, 2025

Resource exhaustion in Internet Systems Consortium Stork 1.0.0 through 2.3.0 allows remote attackers to crash processes via large UI input. The UI request path accepts unauthenticated oversized input and allocates memory for it; repeated smaller inputs also consume log storage, although ISC has not disclosed the exact endpoint or handler. No account is required, and successful exploitation can terminate stork-server or other processes or fill available log storage.
