Impact
The vulnerable /webapi/proxy endpoint accepted a URL supplied in the POST body and fetched it server‑side without requiring any authentication. This Server‑Side Request Forgery permits an attacker to direct the LobeHub server to contact arbitrary external or internal destinations, potentially leaking Vercel deployment details and enabling reflected Set‑Cookie header injection that can affect the lobehub.com domain.
Affected Systems
All LobeHub installations supplied by the lobehub vendor with versions prior to 2.1.57. The vulnerability resides in the /webapi/proxy endpoint exposed on app.lobehub.com.
Risk and Exploitability
The CVSS score of 9 indicates a critical severity. Because the endpoint is unauthenticated, any remote system that can reach the API can trigger exploitation. The EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog. An attacker can initiate arbitrary outbound requests, exfiltrate data, or inject malicious Set‑Cookie headers, making this flaw highly actionable by threat actors.
