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 · unedited
The API in SUSE openSUSE Build Service (OBS) 2.0.x before 2.0.8 and 2.1.x before 2.1.6 allows attackers to bypass intended write-access restrictions and modify a (1) package or (2) project via unspecified vectors.

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 · high confidence

The openSUSE Build Service API fails to enforce write-access controls, allowing authenticated or unauthenticated attackers to modify packages and projects they should not have permission to alter. This is an authorization bypass in the API layer affecting versions 2.0.x before 2.0.8 and 2.1.x before 2.1.6.

MitigationUpgrade to openSUSE Build Service version 2.0.8, 2.1.6, or later to obtain the patch that corrects the access control logic in the API.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed openSUSE Build Service version
    Query the package manager for the obs-server package version (e.g., rpm -qa | grep obs-server or dpkg -l | grep obs-server). Alternatively, check the API endpoint /build/_pacakge or consult the configuration file in /etc/buildservice or the version file in the application directory.
    Affected if The installed version is 2.0.x before 2.0.8, or 2.1.x before 2.1.6, or matches one of the listed affected versions (2.0, 2.0.0-2.0.7, 2.0.16, 2.0.103, 2.0.104).
  2. Confirm the API component is enabled
    Check if the OBS API service is running and listening on its configured port (typically port 80 or 443 for webui, port 5252 for the API daemon). Use commands like netstat -tlnp or ss -tlnp to list listening services, or check the obs-api service status if using systemd.
    Affected if The API daemon (obs-api) is running and accepting connections.
  3. Verify the API is network-accessible
    Attempt to reach the API endpoint locally (curl http://localhost:5252 or the configured API port) or check firewall rules and network configuration to determine if the API port is exposed to network clients.
    Affected if The API port is open and reachable from network clients (authenticated or unauthenticated).
  4. Check for write-access control enforcement in API requests
    Review API access control logs or attempt a controlled test request to modify a package or project using an account without permissions. Examine the API configuration files (typically in /etc/buildservice or /srv/obs/build) for the enforce_permissions or authorization settings.
    Affected if The API allows write operations to packages or projects without proper authorization validation, or the enforce_permissions setting is missing or disabled.

A system is affected if it runs an openSUSE Build Service version 2.0.x before 2.0.8 or 2.1.x before 2.1.6 with the API component enabled and accessible, where write-access controls are not being enforced.
