Base vector

AV:N/AC:L/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions BigSweetPotatoStudio HyperChat versions prior to 2.0.0-alpha.64

Description A server-side request forgery (SSRF) issue exists in the AI Proxy Middleware component. The fetch() function within the packages/core/src/http/aiProxyMiddleware.mts file does not properly handle the baseurl variable, allowing a remote attacker to manipulate it to trigger unauthorized requests from the server.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, restrict access to the AI Proxy Middleware component or avoid using the baseurl parameter in the affected function.
