Published

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`](https://crates.io/crates/uzers) (an actively maintained fork of the `users` crate) - [`sysinfo`](https://crates.io/crates/sysinfo)

Affected versions, risk and source history

Exploitation and risk

Source status

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Risk history

Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.

When does an EPSS score appear as a change?

A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.

Advisory history

16 saved versions

See how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.

How advisory history works

Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
