CVE-2026-35370
uutils coreutils id Incorrect Access-Control Decisions via Misrepresented Group Membership
CVSS Score
4.4
EPSS Score
0.0%
EPSS Percentile
0th
The id utility in uutils coreutils miscalculates the groups= section of its output. 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.
