Doc Text:
Docker Compose is vulnerable to a path traversal flaw in how it handles OCI artifact layer annotations. When processing remote OCI compose artifacts, Compose trusts attacker-controlled annotation fields such as com.docker.compose.extends and com.docker.compose.envfile. This allows a crafted artifact to escape the cache directory and overwrite arbitrary files on the host system, potentially leading to compromise of system integrity.

Description OSIDB Bzimport 2025-10-27 21:01:32 UTC 
Docker Compose trusts the path information embedded in remote OCI compose artifacts. When a layer includes the annotations com.docker.compose.extends or com.docker.compose.envfile, Compose joins the attacker‑supplied value from com.docker.compose.file/com.docker.compose.envfile with its local cache directory and writes the file there. This affects any platform or workflow that resolves remote OCI compose artifacts, Docker Desktop, standalone Compose binaries on Linux, CI/CD runners, cloud dev environments is affected. An attacker can escape the cache directory and overwrite arbitrary files on the machine running docker compose, even if the user only runs read‑only commands such as docker compose config or docker compose ps. This issue is fixed in v2.40.2.
