Description

As part of our Security Development Lifecycle, a potential privilege escalation issue was identified internally. This could allow a malicious actor with sufficient permissions to modify environment variables and abuse an impacted plugin in order to escalate privileges. We have resolved the issue and also made several defense-in-depth fixes alongside. While the probability of successful exploitation is low, Tenable is committed to securing our customers’ environments and our products.
