How to Fix GHSA-82hm-vh7g-hrh9

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

molecule fixed: 0.7.2 
Upgrade molecule to 0.7.2
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 molecule

How to Check if You Are Affected

To determine whether your application is affected by GHSA-82hm-vh7g-hrh9, inspect your project dependencies for Molecule:

inspect dependencies for molecule

Analyze the terminal output to locate any version of Molecule in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.2), 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 Molecule, 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

### Impact Anyone who uses `total_size(..)` function to partial read the length of any `FixVec` will get an incorrect result, due to an incorrect implementation. This has been resolved in the 0.7.2 release. ### Workarounds If you already have the whole `FixVec` `A`, you can use `A.as_slice().len()` to get the total size of the `FixVec`. ### For more information If you have any questions or comments about this advisory: - [Open an issue to ask use directly](https://github.com/nervosnetwork/molecule/issues/new).
