How to Fix GHSA-wm8x-php5-hvq6

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

maligned fixed: Latest secure release 
Upgrade maligned 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 maligned

How to Check if You Are Affected

To determine whether your application is affected by GHSA-wm8x-php5-hvq6, inspect your project dependencies for Maligned:

inspect dependencies for maligned

Analyze the terminal output to locate any version of Maligned 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 Maligned, 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

`maligned::align_first` manually allocates with an alignment larger than T, and then uses `Vec::from_raw_parts` on that allocation to get a `Vec<T>`. [`GlobalAlloc::dealloc`](https://doc.rust-lang.org/std/alloc/trait.GlobalAlloc.html#tymethod.dealloc) requires that the `layout` argument must be the same layout that was used to allocate that block of memory. When deallocating, `Box` and `Vec` may not respect the specified alignment and can cause undefined behavior.
