What is CVE-2026-0824?

CVE-2026-0824 is a low-severity cross-site scripting (XSS) vulnerability in @questdb/web-console (npm), affecting versions < 1.1.10. It is fixed in 1.1.10. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.

How severe is CVE-2026-0824?

CVE-2026-0824 has a CVSS score of 3.5 (Low). 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 @questdb/web-console are affected by CVE-2026-0824?

@questdb/web-console (npm) versions < 1.1.10 is affected.

Is there a fix for CVE-2026-0824?

Yes. CVE-2026-0824 is fixed in 1.1.10. Upgrade to this version or later.

Is CVE-2026-0824 exploitable, and should I be worried?

Whether CVE-2026-0824 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-2026-0824 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.

Summary

QuestDB UI's Web Console is Vulnerable to Cross-Site Scripting

A security flaw has been discovered in questdb ui up to 1.11.9. Impacted is an unknown function of the component Web Console. The manipulation results in cross site scripting. The attack can be executed remotely. The exploit has been released to the public and may be used for attacks. Upgrading to version 1.1.10 is recommended to address this issue. The patch is identified as b42fd9f18476d844ae181a10a249e003dafb823d. You should upgrade the affected component. The vendor confirmed early that the fix "is going to be released as a part of QuestDB 9.3.0" as well.

Impact

Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.

CVE-2026-0824 has a CVSS score of 3.5 (Low). 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 (1.1.10); upgrading removes the vulnerable code path.

Affected versions

@questdb/web-console (< 1.1.10)

Security releases

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.
