OliveTin has unauthenticated DoS via concurrent map writes in OAuth2 state handling

Summary An unauthenticated denial-of-service vulnerability exists in OliveTin’s OAuth2 login flow. Concurrent requests to /oauth/login can trigger unsynchronized access to a shared registeredStates map, causing a Go runtime panic fatal error: concurrent map writes and process termination. This...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the registeredStates map used during OAuth2 state handling. An attacker can cause the service to crash and become unavailable by sending multiple concurrent requests to the...

CVE-2026-27167

A flaw was found in Gradio. When Gradio applications run outside of Hugging Face Spaces and use OAuth components, they automatically enable "mocked" OAuth routes. A remote attacker can exploit this by visiting the /login/huggingface endpoint, which causes the server to retrieve its Hugging Face H...

GHSA-PFJF-5GXR-995X Gradio has an Open Redirect in its OAuth Flow

Summary The redirecttotarget function in Gradio's OAuth flow accepts an unvalidated targeturl query parameter, allowing redirection to arbitrary external URLs. This affects the /logout and /login/callback endpoints on Gradio apps with OAuth enabled i.e. apps running on Hugging Face Spaces with...

Gradio: Mocked OAuth Login Exposes Server Credentials and Uses Hardcoded Session Secret

Summary Gradio applications running outside of Hugging Face Spaces automatically enable "mocked" OAuth routes when OAuth components e.g. gr.LoginButton are used. When a user visits /login/huggingface, the server retrieves its own Hugging Face access token via huggingfacehub.gettoken and stores it...
