What is CVE-2020-26943?

CVE-2020-26943 is a medium-severity code injection vulnerability in blazar-dashboard (pip), affecting versions < 1.3.1. It is fixed in 1.3.1, 2.0.1, 3.0.1. Untrusted input is evaluated as executable code within the application's runtime environment.

How severe is CVE-2020-26943?

CVE-2020-26943 has a CVSS score of 9.9 (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 blazar-dashboard are affected by CVE-2020-26943?

blazar-dashboard (pip) versions < 1.3.1 is affected.

Is there a fix for CVE-2020-26943?

Yes. CVE-2020-26943 is fixed in 1.3.1, 2.0.1, 3.0.1. Upgrade to this version or later.

Is CVE-2020-26943 exploitable, and should I be worried?

Whether CVE-2020-26943 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-2020-26943 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

Arbitrary Code Execution in blazar-dashboard

An issue was discovered in OpenStack blazar-dashboard before 1.3.1, 2.0.0, and 3.0.0. A user allowed to access the Blazar dashboard in Horizon may trigger code execution on the Horizon host as the user the Horizon service runs under (because the Python eval function is used). This may result in Horizon host unauthorized access and further compromise of the Horizon service. All setups using the Horizon dashboard with the blazar-dashboard plugin are affected.

Impact

Untrusted input is evaluated as executable code within the application's runtime environment. Typical impact: arbitrary code execution within the application's privilege context.

CVE-2020-26943 has a CVSS score of 9.9 (Medium). The vector is network-reachable, low 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 (1.3.1, 2.0.1, 3.0.1); upgrading removes the vulnerable code path.

Affected versions

blazar-dashboard (< 1.3.1) blazar-dashboard (= 2.0.0) blazar-dashboard (= 3.0.0)

Security releases

blazar-dashboard → 1.3.1 (pip) blazar-dashboard → 2.0.1 (pip) blazar-dashboard → 3.0.1 (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.
