How to Fix GHSA-gfgm-chr3-x6px

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

prettytable-rs fixed: 0.10.0 
Upgrade prettytable-rs to 0.10.0
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 prettytable-rs

How to Check if You Are Affected

To determine whether your application is affected by GHSA-gfgm-chr3-x6px, inspect your project dependencies for prettytable-rs:

inspect dependencies for prettytable-rs

Analyze the terminal output to locate any version of prettytable-rs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.10.0), 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 prettytable-rs, 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

In function `Table::as_ref`, a reference of vector is force cast to slice. There are multiple problems here: 1. To guarantee the size is correct, we have to first do `Vec::shrink_to_fit`. The function requires a mutable reference, so we have to force cast from immutable to mutable, which is undefined behavior (UB). 2. Even if (1) is sound, `&Vec<T>` and `&[T]` still might not have the same layout. Treating them equally may lead to undefinted behavior (UB).
