Summary
prettytable-rs: Force cast a &Vec<T> to &[T] may lead to undefined behavior
In function Table::as_ref, a reference of vector is force cast to slice. There are multiple problems here:
- 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). - 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).

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

- What is GHSA-GFGM-CHR3-X6PX? GHSA-GFGM-CHR3-X6PX is a medium-severity security vulnerability in prettytable-rs (rust), affecting versions < 0.10.0. It is fixed in 0.10.0.
- Which versions of prettytable-rs are affected by GHSA-GFGM-CHR3-X6PX? prettytable-rs (rust) versions < 0.10.0 is affected.
- Is there a fix for GHSA-GFGM-CHR3-X6PX? Yes. GHSA-GFGM-CHR3-X6PX is fixed in 0.10.0. Upgrade to this version or later.
- Is GHSA-GFGM-CHR3-X6PX exploitable, and should I be worried? Whether GHSA-GFGM-CHR3-X6PX is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-GFGM-CHR3-X6PX is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
