Summary
The `sec-gemini` crate on crates.io was removed for malicious code that tried to send telemetry from the build environment to an arbitrary URL. Because no CVSS vector or advisory impact data is given, the page should not describe a specific attacker capability beyond this data exfiltration attempt.

Read the original description
sec-gemini attempted to send telemetry from the build environment to an arbitrary URL.
The malicious crate had 1 versions published on 2025-06-19, approximately 17 months before removal, and had no evidence of actual usage. This crate had no dependencies on crates.io.
Thanks to Bitbison for the report.

What would change the score
- Would score about 70 if added to CISA KEV
- Would score about 65 if CISA's SSVC rates exploitation active
- Would score about 37 if advisories confirm default setups are exposed
Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by RUSTSEC-2026-0471 (`sec-gemini` was removed from crates.io for malicious code), using the cve.now data below. Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only. What cve.now has for RUSTSEC-2026-0471 (entry last updated 2026-11-10): Affected: - crates.io package sec-gemini: from 0.0.0-0 Fixed versions: none listed yet. Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory. CISA KEV: RUSTSEC-2026-0471 is not listed as of cve.now's last read. This KEV status is for RUSTSEC-2026-0471 only. If you also check another CVE, look up its own KEV status; never assume it from this one. How to check: - Packages (crates.io): find every lockfile in each project and run check_stack from the cve.now MCP server on each one. Compare the resolved versions, not the ranges a manifest declares, with the affected versions above. Include transitive dependencies. Verify against the linked advisories before concluding, and cite the date you read each one: - https://rustsec.org/advisories/RUSTSEC-2026-0471.html - https://crates.io/crates/sec-gemini Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing. Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action. Entry: https://cve.now/RUSTSEC-2026-0471 For follow-up questions, use the cve.now MCP server at https://mcp.cve.now/mcp (no authentication), for example get_vulnerability with id RUSTSEC-2026-0471.

Questions about RUSTSEC-2026-0471
Is RUSTSEC-2026-0471 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
