CVE-2026-4837

Eval Injection in Rapid7 Insight Agent

Published Apr 8, 2026 CVSS 3.1 · 6.6 Medium EPSS < 1% KEV · Not listed
Description
An eval() injection vulnerability in the Rapid7 Insight Agent beaconing logic for Linux versions could theoretically allow an attacker to achieve remote code execution as root via a crafted beacon response. Because the Agent uses mutual TLS (mTLS) to verify commands from the Rapid7 Platform, it is unlikely that the eval() function could be exploited remotely without prior, highly privileged access to the backend platform.
