Vulnerability

no patched versions

Description

The time_calibrators crate attempted to exfiltrate .env files to a server that was in turn impersonating the legitimate timeapi.io service.

The malicious crate had 1 version published on 2026-03-03 approximately 3 hours before removal and had no evidence of actual downloads. There were no crates depending on this crate on crates.io.

Thanks to cybergeek for finding and reporting this to the Rust security response working group, and thanks to Emily Albini for co-ordinating with the crates.io team.
