Description

Summary

A security vulnerability has been detected that allows attackers to bypass authorization plugins (AuthZ) under specific circumstances. The base likelihood of this being exploited is low.

This is an incomplete fix for CVE-2024-41110.

Impact

If you don't use AuthZ plugins, you are not affected.

Using a specially-crafted API request, an attacker could make the Docker daemon forward the request to an authorization plugin without the body. The authorization plugin may allow a request which it would have otherwise denied if the body had been forwarded to it.

Anyone who depends on authorization plugins that introspect the request body to make access control decisions is potentially impacted.

Workarounds

If unable to update immediately:

  • Avoid using AuthZ plugins that rely on request body inspection for security decisions.
  • Restrict access to the Docker API to trusted parties, following the principle of least privilege.

Description

Summary

A race condition during docker cp mount setup allows a malicious container to redirect a bind mount target to an arbitrary host path, potentially overwriting host files or causing denial of service.

Details

When copying files into a container, the daemon sets up a temporary filesystem view by bind-mounting volumes into a private mount namespace. During this setup, the mount destination is created inside the container root and then a bind mount is attached using the container-relative path resolved to an absolute host path.

Between mountpoint creation and the mount() syscall, a process running inside the container can replace the destination (or a parent path component) with a symlink pointing to an arbitrary location on the host. The mount() syscall follows the symlink, causing the volume to be bind-mounted onto an arbitrary host path instead of the intended container path.

Impact

A malicious container can redirect a volume bind mount to an arbitrary host path. The impact depends on the volume content and mount options:

  • If the volume is writable, arbitrary host files at the redirected path could be overwritten with the volume's contents.
  • If the volume is read-only, the host path is masked by the mount for the duration of the operation, causing denial of service.
  • In all cases the mount is temporary (torn down after the docker cp completes), but the effects of any writes persist.

Conditions for exploitation

  • A container must have at least one volume mount.
  • A process inside the container must be able to rapidly create and swap symlinks at the volume mount destination path.
  • An operator must initiate a docker cp into that container, or call the PUT /containers/{id}/archive or HEAD /containers/{id}/archive API endpoints.

Not affected

  • Containers that do not have volume mounts are not affected, as the race occurs during volume bind-mount setup.

Workarounds

  • Only run containers from trusted images.
  • Avoid using docker cp with untrusted running containers.
  • Use authorization plugins to restrict access to the archive API endpoints (PUT /containers/{id}/archive, HEAD /containers/{id}/archive).

Description

Summary

When a user uploads a compressed archive into a container, a malicious image can execute arbitrary code with daemon (host root) privileges.

Details

When handling PUT /containers/{id}/archive requests with compressed archives, the daemon decompresses them using external system binaries. Due to incorrect ordering of operations, these binaries are resolved from the container's filesystem rather than the host's. A container image that includes a trojanized decompression binary can achieve code execution as the daemon process whenever a compressed archive is uploaded to that container.

The executed binary runs with the daemon's full privileges, including host root UID and unrestricted capabilities.

Impact

Arbitrary code execution as host root, crossing the container-to-host trust boundary.

Conditions for exploitation

  • A user must run a container from a malicious image that contains a trojanized decompression binary.
  • The user must then upload a compressed archive (xz or gzip) into that container, either by piping a compressed archive via docker cp - or by calling the PUT /containers/{id}/archive API directly with compressed content.

Not affected

Standard docker cp usage is not affected, because the CLI sends uncompressed tar by default:

docker cp ./file.txt mycontainer:/file.txt

This can only be exploited when explicitly passing a xz or gzip-compressed archive to docker cp or the PUT /containers/{id}/archive API, for example:

cat archive.tar.xz | docker cp - mycontainer:/dir

Decompression formats using pure Go implementations (bzip2, zstd, and gzip when the container image does not contain an unpigz binary) are also not affected.

Workarounds

  • Only run containers from trusted images.
  • Use authorization plugins to limit access to the PUT /containers/{id}/archive endpoint.
  • Avoid piping compressed archives into containers created from untrusted images.

Description

Summary

A security vulnerability has been detected that allows plugins privilege validation to be bypassed during docker plugin install. Due to an error in the daemon's privilege comparison logic, the daemon may incorrectly accept a privilege set that differs from the one approved by the user.

Plugins that request exactly one privilege are also affected, because no comparison is performed at all.

Impact

If plugins are not in use, there is no impact.

When a plugin is installed, the daemon computes the privileges required by the plugin's configuration and compares them with the privileges approved during installation. A malicious plugin can exploit this bug so that the daemon accepts privileges that differ from what was intended to be approved.

Anyone who depends on the plugin installation approval flow as a meaningful security boundary is potentially impacted.

Depending on the privilege set involved, this may include highly sensitive plugin permissions such as broad device access.

For consideration: exploitation still requires a plugin to be installed from a malicious source, and Docker plugins are relatively uncommon. Docker Desktop also does not support plugins.

Workarounds

If unable to update immediately:

  • Do not install plugins from untrusted sources
  • Carefully review all privileges requested during docker plugin install
  • Restrict access to the Docker daemon to trusted parties, following the principle of least privilege
  • Avoid relying on plugin privilege approval as the only control boundary for sensitive environments

Description

Summary

A race condition during docker cp mount setup allows a malicious container to create empty files or directories at arbitrary absolute paths on the host filesystem.

This advisory covers the race during mountpoint creation. The related race during the subsequent mount syscall is tracked in GHSA-rg2x-37c3-w2rh

Details

When copying files into a container, the daemon sets up a temporary filesystem view by bind-mounting volumes into a private mount namespace. During this setup, the mount destination path is first resolved within the container's root filesystem using GetResourcePath, and then used to create the mountpoint (file or directory) if it does not already exist via createIfNotExists.

Between path resolution and mountpoint creation, a process running inside the container can swap a path component for a symlink pointing to an arbitrary location on the host. Because createIfNotExists operates on the already-resolved absolute path using standard os.MkdirAll and os.OpenFile — which follow symlinks in intermediate path components — the symlink is followed and the file or directory is created outside the container root filesystem, as root.

Impact

A malicious container can create empty files or directories at arbitrary absolute paths on the host filesystem, running as root. This enables persistent denial of service — for example:

  • Converting /etc/docker/daemon.json into a directory prevents the daemon from restarting
  • Creating /etc/nologin prevents user logins
  • Overwriting critical system paths with empty files can break host services

The container does not gain read or write access to existing host files — only the ability to create new empty files or directories at chosen paths.

Conditions for exploitation

  • A container must be running with a process that can rapidly create and swap symlinks at a volume mount destination path.
  • An operator must initiate a docker cp into that container, or call the PUT /containers/{id}/archive or HEAD /containers/{id}/archive API endpoints.

Not affected

  • Containers that do not have volume mounts are not affected, as the race occurs during volume bind-mount setup.

Patches

Mountpoint creation is now scoped to the container root using os.Root (Go 1.24+), which refuses to follow symlinks that escape the opened root directory. All filesystem operations in createIfNotExists (MkdirAll, OpenFile) are performed through the os.Root handle, so even if a symlink swap occurs after path resolution, the creation stays confined to the container root.

Workarounds

  • Only run containers from trusted images.
  • Avoid using docker cp with untrusted running containers.
  • Use authorization plugins to restrict access to the archive API endpoints (PUT /containers/{id}/archive, HEAD /containers/{id}/archive).

Description

Impact

A symlink traversal issue in go-git could allow worktree operations to modify files outside the intended worktree path.

The worktreeFilesystem wrapper rejected dangerous path strings, including paths containing .git, parent-directory components, or control characters. However, it did not prevent filesystem operations from following symbolic links that were already present in the worktree.

As a result, a path that is safe when evaluated as a string could still resolve into the repository's Git metadata directory. For example, if s is a symbolic link to .git, writing to s/config would modify .git/config.

A symbolic link at the final path component could also be followed. For example, if s points directly to .git/config, opening s for writing with truncation could overwrite the repository configuration.

Exploitation requires an attacker to be able to introduce or control a symbolic link in the worktree and cause the application to perform a write through that path.

Applications using storage/memory for their Storer, or go-billy/memfs for their Worktree, are not affected by this vulnerability.

Patches

The issue has been addressed by making the worktree filesystem wrapper a symlink-safe boundary.

Worktree operations now reject paths where an existing symbolic link in any path component could cause the operation to escape the intended worktree location, including symbolic links at the final component.

Users of filesystem-backed worktrees should upgrade to a patched version.

EPSS Score0.349%
EPSS Percentile28th percentile
Description

Impact

A path traversal issue in go-git could allow malicious reference names to access files outside the repository's intended reference storage.

Loose references are stored under .git/<reference-name>. The reference name was previously used as a path without verifying that the resolved path remained within the reference storage. A name such as refs/heads/../../config could therefore resolve to unrelated repository metadata such as .git/config or .git/HEAD.

A malicious Git server could advertise such a reference name. The name may also survive refspec mapping; for example, it could be mapped to refs/remotes/origin/../../config during a clone or fetch operation.

This vulnerability affects filesystem-backed repositories using the storage/filesystem package and its dotgit reference storage. Users relying exclusively on the in-memory storage implementation, storage/memory, are not affected, because reference names are not resolved as filesystem paths.

Exploitation requires an application using go-git with filesystem-backed storage to interact with a malicious Git server or otherwise process attacker-controlled reference names.

Patches

The issue has been addressed by validating reference names at the dotgit storage entry points and rejecting names whose resolved paths could escape the reference storage.

Users of filesystem-backed storage should upgrade to a patched version.

Workarounds

Applications that exclusively use storage/memory are not affected and do not require a workaround for this vulnerability.

For applications using filesystem-backed storage, avoid cloning from or fetching from untrusted Git servers until an upgrade is possible.

Applications that directly construct or process reference names may also validate them before passing them to filesystem-backed go-git storage. Application-level validation should only be considered a temporary mitigation and does not replace upgrading to a patched version.
