CVE-2026-82641Public exploitNetwork attack vector

TLS session-key disclosure via unauthenticated agent server

Published Aug 30, 2026 · Updated Aug 30, 2026

Missing authentication in Keploy 3.1.0 through 3.6.25 allows remote attackers to read TLS session keys through the agent HTTP server. The control plane binds to all interfaces and registers /agent/pcap/keylog, /agent/stop, and /agent/storemocks without authentication, streaming NSS keylog lines and accepting state-changing requests. Network access to the dynamic agent port is sufficient to decrypt captured recording traffic, terminate a session, or inject mock data; no credentials or user interaction are required.
