Security readout for executives and security teams
Plain-English summary
CVE-2026-28416 is a high-severity SSRF issue in Gradio before 6.6.0. If an application uses `gr.load()` to load an attacker-controlled Gradio Space, the attacker can cause the server to make unintended HTTP requests, potentially reaching internal services or cloud metadata from the victim environment.
Executive priority
Treat this as a prompt upgrade for affected Gradio deployments, especially internet-facing AI apps or systems in cloud environments. The main business risk is unintended access to internal endpoints through trusted server infrastructure.
Technical view
Gradio trusted a `proxy_url` value from a loaded Space configuration and added it to an allowlist during `gr.load()` processing. This allowed arbitrary server-side HTTP requests from the victim server context. The issue is categorized as CWE-918 and is fixed in Gradio 6.6.0.
Likely exposure
Exposure is most likely in Python applications using Gradio versions earlier than 6.6.0 and calling `gr.load()` on Spaces or sources not fully controlled by the application owner.
Exploitation context
The provided sources describe remote, unauthenticated SSRF with low complexity and no user interaction in CVSS terms. They do not state active exploitation, and the CVE is not marked as KEV in the supplied data.
Researcher notes
Evidence is limited to the CVE record and GitHub advisory. The key validation point is whether vulnerable versions use `gr.load()` with attacker-controlled Spaces. No public exploit status or additional affected products are provided in the source bundle.
Mitigation direction
- Upgrade Gradio to version 6.6.0 or later.
- Avoid loading untrusted or attacker-controlled Spaces with `gr.load()`.
- Review vendor advisory for any updated remediation guidance.
- Restrict server egress to internal services and metadata endpoints where feasible.
Validation and detection
- Inventory applications and containers using the Gradio Python package.
- Confirm installed Gradio versions are 6.6.0 or later.
- Search code for `gr.load()` usage.
- Identify whether loaded Spaces are externally controlled or user-supplied.
- Review egress controls protecting internal services and cloud metadata endpoints.
