How to Fix GHSA-8q64-wrfr-q48c

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

model fixed: Latest secure release 
Upgrade model 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 model

How to Check if You Are Affected

To determine whether your application is affected by GHSA-8q64-wrfr-q48c, inspect your project dependencies for Model:

inspect dependencies for model

Analyze the terminal output to locate any version of Model 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 CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. In Model, 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

`Shared` data structure in `model` crate implements `Send` and `Sync` traits regardless of the inner type. This allows safe Rust code to trigger a data race, which is undefined behavior in Rust. Users are advised to treat `Shared` as an unsafe type. It should not be used outside of the testing context, and care must be taken so that the testing code does not have a data race besides a race condition that is expected to be caught by the test. Check [the Rustonomicon](https://doc.rust-lang.org/nomicon/races.html) for the difference between a data race and a general race condition.
