CVE-2025-15558 Affecting cosign-fips package, versions <3.0.5-r2

Note: Versions mentioned in the description apply only to the upstream cosign-fips package and not the cosign-fips package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Docker 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 29.1.5 and Windows binaries acting as a CLI-plugin manager using the github.com/docker/cli/cli-plugins/manager https://pkg.go.dev/github.com/docker/cli@v29.1.5+incompatible/cli-plugins/manager  package, such as Docker Compose.

This issue does not impact non-Windows binaries, and projects not using the plugin-manager code.
