    matrix-media-repo: Unsafe media served inline on download endpoints

    CVE-2023-41318 · GHSA-5crw-6j7v-xc72

    Affected
    • Go github.com/turt2live/matrix-media-repo < 1.3.0
    Fixed in
    1.3.0· Vendor fix available
    Issue
    Impact A malicious user can upload an SVG image containing JavaScript to their server. When matrix-media-repo is asked to serve that media via the /matrix/media/(r0|v3)/download endpoint, it would be served with a Content-Disposition of inline. This can allow JavaScript to run in the browser if a client links to the /download endpoint directly. Server operators which do not share a domain between matrix-media-repo and other services are not affected, but are encouraged to upgrade regardless. Patches https://github.com/turt2live/matrix-media-repo/commit/77ec2354e8f46d5ef149d1dcaf25f51c04149137 and https://github.com/turt2live/matrix-media-repo/commit/bf8abdd7a5371118e280c65a8e0ec2b2e9bdaf59 fix the issue. Operators should upgrade to v1.3.0 as soon as possible. Workarounds The Content-Disposition header can be overridden by the reverse proxy in front of matrix-media-repo to always use attachment, defeating this issue at the cost of "worse" user experience when clicking download links.…

    Recommended action: Upgrade to 1.3.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
