CVE-2026-5562
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was identified in provectus kafka-ui up to 0.7.2. This impacts the function validateAccess of the file /api/smartfilters/testexecutions of the component Endpoint. The manipulation leads to code injection. The attack can be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA code injection vulnerability exists in provectus kafka-ui up to version 0.7.2 in the validateAccess function of the /api/smartfilters/testexecutions endpoint. The vulnerability allows remote attackers to inject arbitrary code via this API endpoint. The exploit is publicly available and requires no authentication based on the critical CVSS score.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify kafka-ui installation and versionLocate the kafka-ui application and determine its installed version. This can typically be found in the application startup logs, the JAR/WAR file name, a version file, or the application's /actuator/info endpoint if enabled.Affected if The installed version is kafka-ui 0.7.0, 0.7.1, or 0.7.2.
-
Verify the /api/smartfilters/testexecutions endpoint existsConfirm that the kafka-ui web application exposes the /api/smartfilters/testexecutions API endpoint. This can be done by reviewing API documentation, checking network traffic, or attempting to access the endpoint (if safe to do so in a test environment).Affected if The endpoint is present and accessible in the deployment.
-
Confirm validateAccess function is in useThe vulnerability exists in the validateAccess function that processes requests to the /api/smartfilters/testexecutions endpoint. Determine if this function is invoked when the endpoint handles requests - this is the default behavior in affected versions.Affected if The validateAccess function processes input for this endpoint (which is the default behavior in vulnerable versions).
You are affected if you are running kafka-ui version 0.7.0 through 0.7.2 and the /api/smartfilters/testexecutions endpoint is exposed.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate kafka-ui to a version beyond 0.7.2 once available; until then, restrict network access to the affected API endpoint and implement input validation/sanitization at a network perimeter level.
