AI-suggested
Until a fix is available, users should be cautious when relying on rust-coreutils' id output for security-critical decisions and consider using alternative utilities or verifying group membership through other means.
Description
The id utility in the rust-coreutils package incorrectly calculates the groups= section of its output by using the user's real GID instead of the effective GID. This causes the output to diverge from GNU coreutils, potentially leading to incorrect group membership information. Since many scripts and automated processes rely on id's output for security-critical access control or permission decisions, this flaw can result in unauthorized access or security misconfigurations.
