Description

Impact

Server response includes the JWT Secret Key used for signing JWT tokens in error message when the Dispatch Plugin - Basic Authentication Provider plugin encounters an error when attempting to decode a JWT token.

Any Dispatch users who own their instance and rely on the Dispatch Plugin - Basic Authentication Provider plugin for authentication may be impacted, allowing for any account to be taken over within their own instance. This could be done by using the secret to sign attacker crafted JWTs.

If you think that you may be impacted, we strongly suggest you to rotate the secret stored in the DISPATCH_JWT_SECRET envvar in the .env file.

Patches

This issue was fixed in this PR and a new release with the fix was created. Please, upgrade your Dispatch instances to the new version.

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.
