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
Owncast is an open source, self-hosted, decentralized, single user live video streaming and chat server. In versions 0.1.2 and prior, a lenient CORS policy allows attackers to make a cross origin request, reading privileged information. This can be used to leak the admin password. Commit 9215d9ba0f29d62201d3feea9e77dcd274581624 fixes this issue.

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.

How this class of weakness works · CWE-352

The application can't tell whether a state-changing request was genuinely intended by the user, so an attacker can trick a logged-in victim's browser into making it. That can transfer funds, change settings, or create accounts silently. Remediation is anti-CSRF tokens — or equivalent same-site protections — on every state-changing request.

Recommended fix Moderate confidence

Version 0.1.3 or later (the release containing commit 9215d9ba0f29d62201d3fea9e77dcd274581624)

  1. Identify your current Owncast version by checking the admin interface or running `owncast --version`
  2. Stop the Owncast service
  3. Backup your configuration and data directory before proceeding
  4. Pull the latest Owncast container image or download the latest release from https://github.com/owncast/owncast/releases
  5. Deploy the updated version (version 0.1.3 or later, which contains commit 9215d9ba0f29d62201d3feea9e77dcd274581624)
  6. Start the Owncast service
  7. Verify the CORS policy has been hardened by attempting a cross-origin request from an unauthorized domain - this should now be blocked
  8. Log in to the admin interface and confirm functionality
Caveat Review release notes for any configuration changes; may require CORS configuration updates if you had explicitly allowed cross-origin requests
