What is GHSA-9HPW-R23R-XGM5?

GHSA-9HPW-R23R-XGM5 is a high-severity race condition vulnerability in thread_local (rust), affecting versions < 1.1.4. It is fixed in 1.1.4. Multiple concurrent operations access a shared resource without proper synchronization, producing unpredictable results depending on timing.

Which versions of thread_local are affected by GHSA-9HPW-R23R-XGM5?

thread_local (rust) versions < 1.1.4 is affected.

Is there a fix for GHSA-9HPW-R23R-XGM5?

Yes. GHSA-9HPW-R23R-XGM5 is fixed in 1.1.4. Upgrade to this version or later.

Is GHSA-9HPW-R23R-XGM5 exploitable, and should I be worried?

Whether GHSA-9HPW-R23R-XGM5 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-9HPW-R23R-XGM5 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.

Summary

Data race in Iter and IterMut

In the affected version of this crate, {Iter, IterMut}::next used a weaker memory ordering when loading values than what was required, exposing a potential data race
when iterating over a ThreadLocal's values.

Crates using Iter::next, or IterMut::next are affected by this issue.

Impact

Multiple concurrent operations access a shared resource without proper synchronization, producing unpredictable results depending on timing. Typical impact: TOCTOU exploits, data corruption, or privilege escalation.

Affected versions

thread_local (< 1.1.4)

Security releases

thread_local → 1.1.4 (rust)

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.
