Last modified

CVE-2026-82641 is a high-severity vulnerability rated 8.6/10 on the CVSS scale. 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.. EPSS estimates a 0.35% chance of exploitation in the next 30 days.
