Source description

As published by the source; long descriptions are shortened.

It was reported timecalibrator contained malicious code, that would try to upload .env files to a server. The malicious crate had only 1 version published at 2026-02-28 and no evidence of actual usage. The crate was removed from crates.io and the user account was locked. There were no crates depending on this crate on crates.io. Rust security response working group thanks Gabriel Silva for finding and reporting this, and thanks to Emily Albini for co-ordinating with the crates.io and infra-admin teams.

# Patch Next advisory brief: GHSA-77xj-rrh3-wx3v

Advisory: `time_calibrator` was removed from crates.io due to malicious code
IDs: GHSA-77xj-rrh3-wx3v
Record: https://patchnext.com/advisories/ghsa-77xj-rrh3-wx3v (revision 1, source checked 26 Oct 2026, 15:42 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- crates.io time_calibrator: affected every version

## Suggested inspection (read-only)
- crates.io time_calibrator: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on time_calibrator.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
