hoppscotch Vulnerable to Unauthenticated Onboarding Config Takeover

hoppscotch is an open source API development ecosystem. Prior to version 2026.2.0, an unauthenticated attacker can overwrite the entire infrastructure configuration of a self-hosted Hoppscotch instance including OAuth provider credentials and SMTP settings by sending a single HTTP POST request with no authentication. The endpoint POST /v1/onboarding/config has no authentication guard and performs no check on whether onboarding was already completed. A successful exploit allows the attacker to replace the instance's Google/GitHub/Microsoft OAuth application credentials with their own, causing all subsequent user logins via SSO to authenticate against the attacker's OAuth app. The attacker captures OAuth tokens and email addresses of every user who logs in after the exploit. Additionally, the endpoint returns a recovery token that can be used to read all stored secrets in plaintext, including SMTP passwords and any other configured credentials. Version 2026.2.0 fixes the issue.

Hoppscotch 授权问题漏洞

Hoppscotch是Hoppscotch开源的一个开源 Api 开发生态系统。 Hoppscotch 2026.2.0之前版本存在授权问题漏洞，该漏洞源于未经验证的攻击者可通过单个HTTP POST请求覆盖整个基础设施配置，可能导致OAuth凭据和SMTP密码泄露。
