Critical (9.1) in owncast project owncast. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in github.com/owncast/owncast 0.1.3.
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.
