CVE-2026-82641: keploy vulnerability
CVE-2026-82641 affects keploy. 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.
What happened
CVE-2026-82641: 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. 25 bind the agent control-plane HTTP server to all interfaces without authentication, exposing endpoints that stream TLS session keys and traffic data. A security weakness in keploy is being tracked as CVE-2026-82641.
CVE-2026-82641 affects keploy. CVE-2026-82641 currently carries a HIGH 8 6 severity signal in the retained vulnerability data. The important point is that running an affected version of keploy creates exposure, while an actual compromise still depends on whether the attacker can reach the trigger conditions described above.
No exploitation flag is present in the retained CyberDeltaForce data at this time; that status can change as vendor and threat-intelligence reporting develops. 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.
Editorial note: this News Brief follows the available evidence and adds length only when additional facts or useful context are available. Where public reporting does not establish a specific victim sequence, CyberDeltaForce does not present one as fact.
What the reporting and advisory establish
25 bind the agent control-plane HTTP server to all interfaces without authentication, exposing endpoints that stream TLS session keys and traffic data.
CVE-2026-82641 currently carries a HIGH 8.6 severity signal in the retained vulnerability data.
No exploitation flag is present in the retained CyberDeltaForce data at this time; that status can change as vendor and threat-intelligence reporting develops.

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. The issue currently carries a HIGH 8.6 severity signal in the available reporting. There is no reported exploitation in the current available reporting, so the public picture at this point is a disclosed vulnerability with known exploitation conditions rather than a confirmed compromise of every affected installation. The important point is that running an affected version of keploy creates exposure, while an actual compromise still depends on whether the attacker can reach the trigger conditions described above. 25 bind the agent control-plane HTTP server to all interfaces without authentication, exposing endpoints that stream TLS session keys and traffic data.
What this means for your environment
Move from the published facts to the technical path, exposure conditions and defensive decisions that matter in a real environment.
Attack & Exploitation Path
The sequence below shows how the vulnerability can be reached and what successful exploitation can produce. Each stage is labeled by evidence status.
keploy is present and the vulnerable function or code path is reachable in normal application use.
attacker-controlled input or the relevant workflow reaches the the reported vulnerability condition described in the advisory.
the the reported vulnerability condition is triggered inside keploy, creating the security boundary failure described by the advisory.
successful exploitation reaches the confidentiality, integrity or availability impact described in the vendor or vulnerability record.
Why this matters to you
CVE-2026-82641 matters because the practical risk is not the score alone — it is whether keploy exists in your environment and whether the reported trigger or exposure path can reach it. The current severity is HIGH 8.6. No exploitation flag is currently present in the CDF data, but that does not remove the need to validate affected systems.
Does this deserve attention in my environment?
Check the conditions below against your use of keploy.
Select the conditions that are true in your environment. Leaving a condition unselected does not mean you are safe — it only means you have not marked it as applicable.
- Search endpoint, software and asset inventory for keploy.
- Confirm the vendor-recommended fixed version or mitigation and verify deployment, not just assignment, across affected assets.
- Review relevant endpoint, application, network or identity telemetry for activity associated with exploitation of the affected component.
- Track vendor and government guidance for any change in exploitation status while remediation is underway.
What remains unconfirmed
- Available reporting does not currently indicate exploitation, but that can change as vendor, government or threat-intelligence reporting develops.
