Description

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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/owncast/owncast, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/owncast/owncast to 0.1.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-29026 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
