How to Fix GHSA-jcr6-4frq-9gjj

To remediate this vulnerability, upgrade all affected Users dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

users fixed: Latest secure release 
Upgrade users to Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for users

How to Check if You Are Affected

To determine whether your application is affected by GHSA-jcr6-4frq-9gjj, inspect your project dependencies for Users:

inspect dependencies for users

Analyze the terminal output to locate any version of Users in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Users, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Affected versions dereference a potentially unaligned pointer. The pointer is commonly unaligned in practice, resulting in undefined behavior. In some build modes, this is observable as a panic followed by abort. In other build modes the UB may manifest in some other way, including the possibility of working correctly in some architectures. The crate is not currently maintained, so a patched version is not available. ## Recommended alternatives - [`uzers`](https://crates.io/crates/uzers) (an actively maintained fork of the `users` crate) - [`sysinfo`](https://crates.io/crates/sysinfo)
