How to Fix GHSA-r45x-ghr2-qjxc

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

zeroize_derive fixed: 1.1.1 
Upgrade zeroize_derive to 1.1.1
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 zeroize_derive

How to Check if You Are Affected

To determine whether your application is affected by GHSA-r45x-ghr2-qjxc, inspect your project dependencies for Duplicate Advisory:

inspect dependencies for zeroize_derive

Analyze the terminal output to locate any version of Duplicate Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.1), 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-226: Sensitive Information in Resource Not Removed Before Reuse, where the product releases a resource such as memory or a file so that it can be made available for reuse, but it does not clear or "zeroize" the information contained in the resource before the product performs a critical state transition or makes the resource available for reuse by other entities. In Duplicate Advisory, 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

## Duplicate Advisory This advisory is a duplicate of [GHSA-c5hx-w945-j4pq](https://github.com/advisories/GHSA-c5hx-w945-j4pq). This link is preserved to maintain external references. ## Original Description Affected versions of this crate did not implement `Drop` when `#[zeroize(drop)]` was used on an `enum`. This can result in memory not being zeroed out after dropping it, which is exactly what is intended when adding this attribute. The flaw was corrected in version 1.2 and `#[zeroize(drop)]` on `enum`s now properly implements `Drop`.
