SCA: security update for com.alibaba.nacos:nacos-common (GHSA-36hp-jr8h-556f)

critical Tenable Self-Hosted Container Security Plugin ID 409340

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Nacos is a platform designed for dynamic service discovery and configuration and service management. In
 Nacos before version 1.4.1, when configured to use authentication (-Dnacos.core.auth.enabled=true) Nacos
 uses the AuthFilter servlet filter to enforce authentication. This filter has a backdoor that enables
 Nacos servers to bypass this filter and therefore skip authentication checks. This mechanism relies on the
 user-agent HTTP header so it can be easily spoofed. This issue may allow any user to carry out any
 administrative tasks on the Nacos server. (CVE-2021-29441)
