CVE-2026-30955Network attack vector

Authenticated service crash via unbounded E2E metadata

Published Mar 13, 2026 · Updated Mar 13, 2026

Uncontrolled resource consumption in Gokapi before 2.2.4 allows remote authenticated users to crash the server via E2E metadata. The paramE2eStore.ProcessParameter method decodes JSON from the request body without limiting its size, allowing concurrent large bodies to exhaust memory. Any authenticated user can reach the endpoint, and an out-of-memory kill completely interrupts service for all users.
