    sh _uid does not drop supplementary groups (incomplete privilege drop)

    CVE-2026-54552 · GHSA-q38v-wp89-2w55

    Affected
    • PyPI sh < 2.2.4
    Fixed in
    2.2.4· Vendor fix available
    Issue
    Impact The uid option performed an incomplete privilege drop on Linux/Unix-like systems. When sh was run from a process with elevated privileges, such as root, and a command was launched with uid=<unprivileged user, the child process changed its UID and primary GID but did not reset its supplementary groups. As a result, the child process could retain the parent process’s supplementary groups, potentially including privileged groups such as root, docker, disk, shadow, or sudo. This could allow a subprocess that was expected to run with reduced privileges to access files or resources available to the original process’s supplementary groups. Users are impacted if they rely on uid as a privilege boundary when launching commands from a privileged parent process. Patches Upgrade to version = 2.2.4 Workarounds Avoid using uid when the user represents a less-privileged user.

    Recommended action: Upgrade to 2.2.4 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
