Summary
Arrow2 allows out of bounds access in public safe API
Rows::row_unchecked() allows out of bounds access to the underlying buffer without sufficient checks.
The arrow2 crate is no longer maintained, so there are no plans to fix this issue. Users are advised to migrate to the arrow crate, instead.

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.

- Which versions of arrow2 are affected by GHSA-WV8J-M3HX-924J? arrow2 (rust) versions <= 0.18.0 is affected.
- Is there a fix for GHSA-WV8J-M3HX-924J? No fixed version is listed for GHSA-WV8J-M3HX-924J yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is GHSA-WV8J-M3HX-924J exploitable, and should I be worried? Whether GHSA-WV8J-M3HX-924J 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-WV8J-M3HX-924J 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.
