CVE-2026-45317

CVE-2026-45317 is a medium-severity improper input validation vulnerability in open-webui (pip), affecting versions <= 0.9.2. It is fixed in 0.9.3.

Summary

Open WebUI Vulnerable to Cross-Site Request Forgery (CSRF) via Image URL Manipulation

Impact

The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths. Typical impact: varies by context: data corruption, logic bypass, or denial of service.

CVE-2026-45317 has a CVSS score of 4.6 (Medium). The vector is network-reachable, low privileges required, and user interaction required. 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 (0.9.3); upgrading removes the vulnerable code path.

Affected versions

open-webui (<= 0.9.2)

Security releases

open-webui → 0.9.3 (pip)

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

  • Store images

    • Instead of sending a GET request to load the image each time, store the image and render on the page
  • Validate input

    • Image file types should be whitelisted (examples: .jpg, .png, .gif, .jpeg, etc)

Frequently Asked Questions

  1. What is CVE-2026-45317? CVE-2026-45317 is a medium-severity improper input validation vulnerability in open-webui (pip), affecting versions <= 0.9.2. It is fixed in 0.9.3. The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths.
  2. How severe is CVE-2026-45317? CVE-2026-45317 has a CVSS score of 4.6 (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.
  3. Which versions of open-webui are affected by CVE-2026-45317? open-webui (pip) versions <= 0.9.2 is affected.
  4. Is there a fix for CVE-2026-45317? Yes. CVE-2026-45317 is fixed in 0.9.3. Upgrade to this version or later.
  5. Is CVE-2026-45317 exploitable, and should I be worried? Whether CVE-2026-45317 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.

  6. What actually determines whether CVE-2026-45317 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.
  7. How do I fix CVE-2026-45317? Upgrade open-webui to 0.9.3 or later.
