CVE-2026-6948 is a resource exhaustion vulnerability in Rapid7 Velociraptor versions prior to 0.76.4. It affects the server's agent control channel, allowing a compromised or rogue client to cause an out-of-memory (OOM) condition and crash the server by sending crafted messages. The vulnerability does not impact confidentiality or integrity but results in denial of service. The CVSS score is 4.9, indicating medium severity. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
Rapid7 Velociraptor before version 0.76.4 contains a CWE-770 vulnerability where the server allocates resources without limits or throttling in the agent control channel. This flaw allows a malicious client to exhaust server memory by sending specially crafted messages, leading to a denial of service via server crash. The vulnerability requires high privileges on the client side and no user interaction. The CVSS vector is AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H, reflecting network attack vector, low complexity, high privileges required, no user interaction, unchanged scope, no confidentiality or integrity impact, and high availability impact.
Potential Impact
The vulnerability enables denial of service by crashing the Velociraptor server through out-of-memory conditions triggered by malicious client messages. It does not affect confidentiality or integrity of data. The impact is limited to availability disruption of the Velociraptor server component.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, monitor client behavior and restrict access to trusted clients to reduce risk. No official remediation or temporary fix is currently documented by Rapid7.
