Deeper analysis
CVE-2023-3188 is a Server-Side Request Forgery vulnerability (CWE-918) affecting the Owncast GitHub repository prior to version 0.1.0. The flaw received a CVSS 3.1 score of 6.5 and permits an attacker to induce the server into making unauthorized requests to internal or external resources.
An unauthenticated remote attacker can exploit the issue over the network with low complexity to obtain limited read and write access to resources reachable by the Owncast server. Successful exploitation does not require user interaction and can result in information disclosure or limited modification of server-reachable targets.
The referenced commit f40135dbf28093864482f9662c23e478ea192b16 in the Owncast repository addresses the SSRF condition, and the associated huntr.dev report confirms that updating to version 0.1.0 or later mitigates the exposure. The EPSS score has reached 0.5449 without an indicated rise from a lower baseline.
