A Server-Side Request Forgery (SSRF) vulnerability exists in the gradio-app/gradio version 4.21.0, specifically within the `/queue/join` endpoint and the `save_url_to_cache` function. The vulnerability arises when the `path` value, obtained from the user and expected to be a URL, is used to make an HTTP request without sufficient validation checks. This flaw allows an attacker to send crafted requests that could lead to unauthorized access to the local network or the AWS metadata endpoint, thereby compromising the security of internal servers.
A command injection vulnerability exists in the deploy+test-visual.yml workflow of the gradio-app/gradio repository, due to improper neutralization of special elements used in a command. This vulnerability allows attackers to execute unauthorized commands, potentially leading to unauthorized modification of the base repository or secrets exfiltration. The issue arises from the unsafe handling of GitHub context information within a `run` operation, where expressions inside `${{ }}` are evaluated and substituted before script execution. Remediation involves setting untrusted input values to intermediate environment variables to prevent direct influence on script generation.
