Summary
Open WebUI Has Stored Cross-Site Scripting in SVG Renderer
Impact
Cross-Site Scripting allows attacker to execute malicious code in context of victim's browser. This way it could be used in malicious client-side attack achieving different things, depends on attacker's goal. Such thread with rendered SVG could be shared to other user (or administrator) and gain sensitive data or even takeover someone's account.

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.

- What is CVE-2026-45346? CVE-2026-45346 is a medium-severity security vulnerability in open-webui (npm), affecting versions < 0.6.31. It is fixed in 0.6.31.
- Which versions of open-webui are affected by CVE-2026-45346? open-webui (npm) versions < 0.6.31 is affected.
- Is there a fix for CVE-2026-45346? Yes. CVE-2026-45346 is fixed in 0.6.31. Upgrade to this version or later.
- Is CVE-2026-45346 exploitable, and should I be worried? Whether CVE-2026-45346 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-2026-45346 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.
