How to Fix GHSA-pqpw-89w5-82v5

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

simd-json-derive fixed: 0.12.0 
Upgrade simd-json-derive to 0.12.0
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 simd-json-derive

How to Check if You Are Affected

To determine whether your application is affected by GHSA-pqpw-89w5-82v5, inspect your project dependencies for Simd json derive:

inspect dependencies for simd-json-derive

Analyze the terminal output to locate any version of Simd json derive in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.12.0), 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 Simd json derive, 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

An invalid use of `MaybeUninit::uninit().assume_init()` in `simd-json-derive`'s derive macro can cause undefined behavior. The original code used `MaybeUninit` to avoid initialisation of the struct and then set the fields using `ptr::write`. The undefined behavior triggered by this misuse of `MaybeUninit` can lead to invlaid memory access and panics in binaries compiled in release mode (aka simd-json-derive prior to version 0.12 has UB and optimizes into some nonsense) The version `0.12.0` removes this section of code, avoiding the use of MaybeUninit alltogether.
