Description

Summary

The Coverage rest api /workspaces/{workspaceName}/coveragestores/{storeName}/{method}.{format} allow to upload file with a specified url (with {method} equals 'url') with no restrict.

Details

The Coverage rest api /workspaces/{workspaceName}/coveragestores/{storeName}/{method}.{format} allow to upload file with a specified url (with {method} equals 'url'). But this url has not been check with URL Checks feature.

For example, should add the code below to check fileURL:

URLCheckers.confirm(fileURL)

The vulnerable code was RESTUtils.java

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.geoserver:gs-rest, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.geoserver:gs-rest to 2.26.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r4hf-r8gj-jgw2 is resolved across your whole dependency graph.

  3. Workarounds

    Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.
