owncast — Vulnerabilities & Security Advisories 5

Owncast is a self-hosted live video streaming server designed for independent broadcasters to create their own streaming platforms without third-party dependencies. Historically, the project has faced vulnerabilities including remote code execution (RCE), cross-site scripting (XSS), and privilege escalation issues, with five CVEs documented to date. These weaknesses often stem from improper input validation and insufficient access controls in its web interface. While no major public security incidents have been widely reported, the presence of multiple RCE vulnerabilities in past versions highlights the importance of maintaining updated installations and implementing proper network segmentation for deployments.
