CVE-2026-4837 PUBLISHED

Eval Injection in Rapid7 Insight Agent

Assigner: rapid7
Reserved: 25.03.2026 Published: 08.04.2026 Updated: 09.04.2026

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.
