Description

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.
