description

HashiCorp Boundary and Boundary Enterprise Vault credential store integrations are affected by server-side request forgery. An authenticated user permitted to manage project credential stores and credential libraries could cause a controller to request network destinations it can reach and obtain the responses.

mitigation

Upgrade Boundary Enterprise to 1.0.2 or 0.21.6. Until upgraded, restrict permissions to manage credential stores and credential libraries to trusted administrators.

fixed in *, 1.0.2
