How to Fix GHSA-f95p-4cv5-8w8x

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

linkme fixed: 0.3.24 
Upgrade linkme to 0.3.24
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 linkme

How to Check if You Are Affected

To determine whether your application is affected by GHSA-f95p-4cv5-8w8x, inspect your project dependencies for Linkme:

inspect dependencies for linkme

Analyze the terminal output to locate any version of Linkme in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.3.24), 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 Linkme, 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 allow populating a DistributedSlice of T with elements of an arbitrary other type that coerces to T. For example, elements of type `&&str` could end up in a slice of type `[&str]`, since `&&str` coerces to `&str` via a deref coercion. The flaw was corrected by implementing typechecking for distributed slice elements in such a way that coercion no longer occurs. The element's type must be a subtype of the slice's declared element type.
