Exposures › CVE-2026-62327
9Router versions <=0.4.41 leak plaintext API keys via an unauthenticated endpoint, enabling billing fraud and quota exhaustion.
This unauthenticated information disclosure allows remote attackers to retrieve plaintext API keys for all connected AI provider accounts by exploiting missing authentication middleware on the /api/usage/stats endpoint. For DIB organizations, this exposes AI infrastructure used for compliance automation or data processing to unauthorized billing fraud and quota exhaustion, requiring immediate patching and API key rotation. The vulnerability is not RCE but represents a critical data exposure risk for any system integrating AI services.
Shame score — A critical unauthenticated disclosure of plaintext credentials in a widely-used AI router component, though not actively exploited in the wild.
9Router through version 0.4.41 contain an unauthenticated information disclosure vulnerability that allows remote attackers to retrieve plaintext API keys for all connected AI provider accounts by sending a single unauthenticated request to the /api/usage/stats endpoint. Attackers can exploit the missing authentication middleware on the Next.js API route to obtain full API key strings alongside token counts, cost breakdowns, and request metadata, enabling unauthorized use of connected AI provider accounts, billing fraud, and quota exhaustion.
