Vendor Workaround
Avoid opening HLS, DASH, or MSS manifests from untrusted network sources. Run GStreamer-based applications with minimal filesystem access using Linux namespaces or containers, restricting the process to only the directories it legitimately requires. Where feasible, use network controls to limit which manifest hosts the application may contact. These measures reduce risk but do not remove the vulnerability.

| Type | Values Removed | Values Added |

| Description | A flaw was found in GStreamer's adaptive streaming demuxers (HLS, DASH, MSS). When processing a media playlist or manifest, URIs referenced in the manifest content are fetched without restricting which URI schemes are permitted. An attacker who controls a manifest URL, or who can inject content into an HTTP manifest response, can include file:// URIs pointing to arbitrary local files, causing the affected application to read and process those files. In automated or server-side deployments such as media recorders, proxies, and downloaders, this can lead to disclosure of sensitive local files. Existence of files can also be inferred through differing error responses even when content is not directly observable. | |
