The implementation uses a user's real GID instead of their effective GID to compute the group list, leading to potentially divergent output compared to GNU coreutils. Because many scripts and automated processes rely on the output of id to make security-critical access-control or permission decisions, this discrepancy can lead to unauthorized access or security misconfigurations."},{"lang":"es","value":"La utilidad id en uutils coreutils calcula erróneamente la sección groups= de su salida.
