Gravitee API Management before 3.15.13 allows path traversal through HTML injection.

Gravitee API Management through 4.12.22 contains an authentication bypass vulnerability that allows unauthenticated remote attackers to impersonate any user by forging JWTs signed with the shipped default jwt.secret. Attackers knowing an existing user ID can sign an HS256 token with that subject and present it as a bearer token to the Management API, impersonating administrators to gain full platform control.

HTML injection combined with path traversal in the Email service in Gravitee API Management before 1.25.3 allows anonymous users to read arbitrary files via a /management/users/register request.
