Overview
sillytavern is a LLM Frontend for Power Users
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the corsProxyMiddleware function. An attacker can access internal network services or sensitive metadata endpoints by supplying a crafted URL to the GET /proxy/:url(*) endpoint, which is forwarded without sufficient validation.
Note: This is only exploitable if the server is accessible over a network and the private request filter is not enabled and properly configured.
