This issue affects Docker CLI through 29.1.5
// impactDocker CLI for Windows searches for plugin binaries in C:\ProgramData\Docker\cli-plugins, a directory that does not exist by default. A low-privileged attacker can create this directory and place malicious CLI plugin binaries (docker-compose.exe, docker-buildx.exe, etc.) that are executed when a victim user opens Docker Desktop or invokes Docker CLI plugin features, and allow privilege-escalation if the docker CLI is executed as a privileged user.
This issue affects Docker CLI through v29.1.5 (fixed in v29.2.0). It impacts Windows binaries acting as a CLI plugin manager via the github.com/docker/cli/cli-plugins/manager package, which is consumed by downstream projects such as Docker Compose.
Docker Compose became affected starting in v2.31.0, when it incorporated the relevant CLI plugin manager code (see https://github.com/docker/compose/pull/12300), and is fixed in v5.1.0.
This issue does not impact non-Windows binaries or projects that do not use the plugin manager code.
// patchesFixed version starts with 29.2.0
This issue was fixed in https://github.com/docker/cli/commit/13759330b1f7e7cb0d67047ea42c5482548ba7fa (https://github.com/docker/cli/pull/6713), which removed %PROGRAMDATA%\Docker\cli-plugins from the list of paths used for plugin-discovery on Windows.
