7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
Summary
users may append `root` to group listings
Details

Affected versions append root to group listings, unless the correct listing has exactly 1024 groups.

This affects both:

  • The supplementary groups of a user
  • The group access list of the current process

If the caller uses this information for access control, this may lead to privilege escalation.

This crate is not currently maintained, so a patched version is not available.

Versions older than 0.8.0 do not contain the affected functions, so downgrading to them is a workaround.

Recommended alternatives

  • uzers (an actively maintained fork of the users crate)
  • sysinfo
