Title
Simple Admin Core through 1.8.7 Hard-Coded JWT Secret Authentication Bypass
Summary
Simple Admin Core through 1.8.7 contains an authentication bypass vulnerability that allows unauthenticated attackers to forge super administrator tokens by using the hard-coded Auth.AccessSecret in api/etc/core.yaml. Attackers can sign a JWT with the public secret and roleId claim 001 to gain full administrative control over users, roles, menus, API authorities, configuration and tokens.
