Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.

Description

Owncast is an open source, self-hosted, decentralized, single user live video streaming and chat server. The Owncast application exposes an administrator API at the URL /api/admin. The emoji/delete endpoint of said API allows administrators to delete custom emojis, which are saved on disk. The parameter name is taken from the JSON request and directly appended to the filepath that points to the emoji to delete. By using path traversal sequences (../), attackers with administrative privileges can exploit this endpoint to delete arbitrary files on the system, outside of the emoji directory. This vulnerability is fixed in 0.1.3.

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-2024-31450 is resolved across your whole dependency graph.

  3. Workarounds

    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
