Updates

Status

Pending upstream fix

Impact

The vulnerable component is github.com/docker/docker. Per the GitHub Security Advisory at https://github.com/advisories/GHSA-x744-4wpc-v9h2 (Moby has AuthZ plugin bypass when provided oversized request bodies), github.com/docker/docker is listed as affected with no published fixed version (vulnerable range <29.3.1). The advisory's only patched entry is for the separate module path github.com/moby/moby/v2 @ 2.0.0-beta.8, which datadog-agent-7.76 does not vendor. Without an upstream release that fixes the github.com/docker/docker module path, this issue cannot be closed by routine dependency-bump automation. A pending-upstream-fix advisory event is justified: the issue should reflect that we are awaiting either upstream backporting the fix to the github.com/docker/docker module path, or the package migrating to github.com/moby/moby/v2.

Status

Pending upstream fix

Impact

Fix for this CVE is available in Docker Engine v29.3.1 and github.com/moby/moby/v2 v2.0.0-beta.8. A fix has also been committed to the moby/moby 28.x branch (https://github.com/moby/moby/commit/6d311e0d8d4174a6347942db78c553fb7dc3762e) but no release has been tagged yet. No backport to older module versions is available. Awaiting upstream maintainer action.
