CVE-2026-18953: Amazon Aws Transform Mcp Server

High severity, CVSS 8.8. EPSS: 0.2% chance of exploitation in the next 30 days.

Improper limitation of a pathname to a restricted directory in the get_resource tool in Amazon awslabs.aws-transform-mcp-server 0.1.0 through 0.1.4 might allow a context-dependent actor to write arbitrary files outside the intended working directory via the savePath parameter. To remediate this issue, users should upgrade to version 0.1.5 or later.

Affected products

  • Amazon Aws Transform Mcp Server: from 0.1.0, before 0.1.5 (fixed in 0.1.5)
