Impact
This is a vulnerability which affects anyone using Gradio's share links (i.e. creating a Gradio app and then setting share=True) with Gradio versions older than 3.13.1. In these older versions of Gradio, a private SSH key is sent to any user that connects to the Gradio machine, which means that a user could access other users' shared Gradio demos. From there, other exploits are possible depending on the level of access/exposure the Gradio app provides.
Credentials are embedded in source code or a binary, making them accessible to anyone who can read the artifact. Typical impact: unauthorized access using the static credential.
CVE-2023-25823 has a CVSS score of 5.4 (Medium). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (3.13.1); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
Remediation advice
The problem has been patched. Ideally, users should upgrade to gradio==3.19.1 or later where the FRP solution has been properly tested.
Frequently Asked Questions
- What is CVE-2023-25823? CVE-2023-25823 is a medium-severity use of hard-coded credentials vulnerability in gradio (pip), affecting versions < 3.13.1. It is fixed in 3.13.1. Credentials are embedded in source code or a binary, making them accessible to anyone who can read the artifact.
- How severe is CVE-2023-25823? CVE-2023-25823 has a CVSS score of 5.4 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of gradio are affected by CVE-2023-25823? gradio (pip) versions < 3.13.1 is affected.
- Is there a fix for CVE-2023-25823? Yes. CVE-2023-25823 is fixed in 3.13.1. Upgrade to this version or later.
- Is CVE-2023-25823 exploitable, and should I be worried? Whether CVE-2023-25823 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2023-25823 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2023-25823? Upgrade
gradioto 3.13.1 or later.
