CVE-2026-82641 keploy CVE debrief

AI-assisted PatchSiren debrief based on the supplied source corpus. The CVE record was published on 2026-08-30T14:17:04.020Z and has not been modified since then. The vulnerability affects keploy versions 3.1.0 through 3.6.25, exposing endpoints that stream TLS session keys and traffic data due to the agent control-plane HTTP server being bound to all interfaces without authentication. 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. Organizations should verify their deployments, assess potential exposure, and implement compensating controls where necessary. Detailed information about the vendor's response or affected scope is limited in the provided source corpus.

Who should care

Organizations using keploy versions 3.1.0 through 3.6.25, security teams responsible for monitoring and patching vulnerabilities, individuals handling sensitive data with keploy, and operators managing keploy deployments should prioritize assessing and addressing this vulnerability. This includes reviewing system configurations, assessing potential exposure, and implementing compensating controls where necessary.

Technical summary

The keploy agent control-plane HTTP server is bound to all interfaces without authentication in versions 3.1.0 through 3.6.25. This exposes endpoints that stream TLS session keys and traffic data, allowing attackers to 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. Affected organizations should focus on patching or mitigating this vulnerability to prevent potential TLS traffic decryption and manipulation of recording sessions.

Defensive priority

Organizations using keploy versions 3.1.0 through 3.6.25 should prioritize patching or mitigating the vulnerability to prevent potential TLS traffic decryption and manipulation of recording sessions.

Recommended defensive actions

  • Patch keploy to a version outside of 3.1.0 through 3.6.25
  • Implement authentication for the agent control-plane HTTP server
  • Restrict access to the exposed endpoints
  • Monitor for potential exploitation attempts
  • Consider compensating controls for TLS traffic decryption

Evidence notes

The CVE description indicates that keploy versions 3.1.0 through 3.6.25 bind the agent control-plane HTTP server to all interfaces without authentication, exposing endpoints that stream TLS session keys and traffic data. However, detailed information about the vendor's response or affected scope is limited in the provided source corpus. Organizations should verify their deployments and assess potential exposure based on this limited information.
