What is CVE-2025-5791?

A flaw in the 'users' crate for Rust allows for privilege escalation due to incorrect group listing. When a user or process has fewer than 1024 groups, the root group may be mistakenly included in the access list. This security issue can lead to unauthorized access to sensitive operations or data, posing a risk to applications relying on this crate.
