SCA: security update for awslabs.aws-api-mcp-server (GHSA-29w2-fq35-v728)

high Tenable Self-Hosted Container Security Plugin ID 445374

Description

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

 - Improper handling of an initialization failure in AWS API MCP Server from 0.2.13 through 1.3.46 might
 allow an actor to bypass the user-configured security policy and execute AWS API operations that the
 policy was set to deny or gate. When initialization of the security policy enforcement data fails at
 server startup, the policy check is skipped for the lifetime of the process. IAM permissions on the
 configured credentials remain in effect and are unaffected. To remediate this issue, users should upgrade
 to version 1.3.47. (CVE-2026-16584)

Solution

Update the awslabs.aws-api-mcp-server library and its related packages to version 1.3.47 or later.
