Description

In HashiCorp Consul Template through version 0.29.1, invalid templates could inadvertently reveal the contents of Vault secret in errors returned by the *template.Template.Execute 5 method, when given a template using Vault secret contents incorrectly. This method has been updated to redact Vault secrets when creating an error string, making it safe to log the error.. This issue was fixed in version 0.29.2.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
