CVE-2026-82641: Missing authentication for critical function vulnerability

Keploy versions 3.1.0 through 3.6.25, fixed in 3.6.26, bind the agent control-plane HTTP server to all interfaces without authentication, exposing endpoints that stream TLS session keys and traffic data. Attackers can access the /agent/pcap/keylog endpoint to retrieve NSS keylog lines and decrypt recorded TLS traffic, or invoke /agent/stop and /agent/storemocks to manipulate recording sessions.
