CVE-2026-86671: In Eclipse Che versions 7.29.0 and later, the GET `/api/scm/resolve` and `POST /api/factory/resolver` endpoints pass an attacker-controlled URL to `URLFetcher.f

In Eclipse Che versions 7.29.0 and later, the GET `/api/scm/resolve` and `POST /api/factory/resolver` endpoints pass an attacker-controlled URL to `URLFetcher.f

In Eclipse Che versions 7.29.0 and later, the GET `/api/scm/resolve` and `POST /api/factory/resolver` endpoints pass an attacker-controlled URL to `URLFetcher.fetch()`, which calls `new URL(url).openConnection()` with no scheme or host allow-list and returns the response body to the caller. Any authenticated Che user can read arbitrary local files via the file:// scheme (including the pod's Kubernetes service-account token at `file:///var/run/secrets/kubernetes.io/serviceaccount/token`), reach internal HTTP services and cloud instance metadata endpoints (169.254.169.254), and have their stored SCM personal access token attached as an `Authorization` header to a host of their choosing. The same credential-forwarding behavior also fires when a victim opens a workspace from a malicious devfile whose `parent.uri` points to an attacker-controlled server, enabling exfiltration of the victim's SCM PAT without direct API access. No fix is available.

What it means for a small business

If your business uses Eclipse Che, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.25%, higher than 16% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 28, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
