Summary
time-sync was removed from crates.io due to malicious code
The time-sync crate attempted to exfiltrate .env files to a server that was in turn impersonating the legitimate timeapi.io service. This the same attack that we've seen three times in the last few days.
The malicious crate had 1 version published on 2026-03-04 approximately 50 minutes before removal and had no evidence of actual downloads. There were no crates depending on this crate on crates.io.

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-MH23-RW7F-V5PQ? GHSA-MH23-RW7F-V5PQ is a critical-severity security vulnerability in time-sync (rust), affecting versions >= 0. No fixed version is listed yet.
- Which versions of time-sync are affected by GHSA-MH23-RW7F-V5PQ? time-sync (rust) versions >= 0 is affected.
- Is there a fix for GHSA-MH23-RW7F-V5PQ? No fixed version is listed for GHSA-MH23-RW7F-V5PQ yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is GHSA-MH23-RW7F-V5PQ exploitable, and should I be worried? Whether GHSA-MH23-RW7F-V5PQ 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-MH23-RW7F-V5PQ 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.
