Missing JWT signature check (GHSL-2022-078)
The StatelessTokenService of the DataHub metadata service (GMS) does not verify the signature of JWT tokens. This allows an attacker to connect to DataHub instances as any user if Metadata Service authentication is enabled. This vulnerability occurs because the StatelessTokenService of the Metadata service uses the parse method of io.jsonwebtoken.JwtParser, which does not perform a verification of the cryptographic token signature. This means that JWTs are accepted regardless of the used algorithm.
Impact
This issue may lead to an authentication bypass.
