# CVE-2022-46176: cargo: Cargo is a Rust package manager CVE-2022-46176 is fixed in 21 products on 1 platform, first by cargo 0.67.1+ds0ubuntu0.libgit2-0ubuntu0.20.04.2, released January 11, 2023. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2022-46176 - Priority: Routine - CVSS: 5.9 (medium) - EPSS: 0.0068 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Jan 11, 2023 ## Description Cargo is a Rust package manager. The Rust Security Response WG was notified that Cargo did not perform SSH host key verification when cloning indexes and dependencies via SSH. An attacker could exploit this to perform man-in-the-middle (MITM) attacks. This vulnerability has been assigned CVE-2022-46176. All Rust versions containing Cargo before 1.66.1 are vulnerable. Note that even if you don't explicitly use SSH for alternate registry indexes or crate dependencies, you might be affected by this vulnerability if you have configured git to replace HTTPS connections to GitHub with SSH (through git's [`url..insteadOf`][1] setting), as that'd cause you to clone the crates.io index through SSH. Rust 1.66.1 will ensure Cargo checks the SSH host key and abort the connection if the server's public key is not already trusted. We recommend everyone to upgrade as soon as possible. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | cargo Debian 12.15 (bookworm) | 0.66.0+ds1-1 | [DEBIAN-CVE-2022-46176](https://patchblox.com/security/data/fix/linux/debian-cve-2022-46176.md) | Jan 11, 2023 | | Linux | cargo Ubuntu 20.04 LTS (focal) | 0.67.1+ds0ubuntu0.libgit2-0ubuntu0.20.04.2 | [cargo 0.67.1+ds0ubuntu0.libgit2-0ubuntu0.20.04.2](https://patchblox.com/security/data/fix/linux/ubuntu-focal-cargo-0.67.1-ds0ubuntu0.libgit2-0ubuntu0.20.04.2.md) | Jan 11, 2023 | | Linux | cargo Ubuntu 22.04.1 LTS (jammy) | 0.67.1+ds0ubuntu0.libgit2-0ubuntu0.22.04.2 | [cargo 0.67.1+ds0ubuntu0.libgit2-0ubuntu0.22.04.2](https://patchblox.com/security/data/fix/linux/ubuntu-jammy-cargo-0.67.1-ds0ubuntu0.libgit2-0ubuntu0.22.04.2.md) | Jan 11, 2023 | | Linux | cargo amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | cargo-debuginfo amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | clippy amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | clippy-debuginfo amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-analysis amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-analyzer amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-analyzer-debuginfo amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-cargo Debian 12.15 (bookworm) | 0.66.0-1 | [DEBIAN-CVE-2022-46176](https://patchblox.com/security/data/fix/linux/debian-cve-2022-46176.md) | Jan 11, 2023 | | Linux | rust-cargo Debian 13.5 (trixie) | 0.66.0-1 | [DEBIAN-CVE-2022-46176](https://patchblox.com/security/data/fix/linux/debian-cve-2022-46176.md) | Jan 11, 2023 | | Linux | rust-cargo Debian 14 | 0.66.0-1 | [DEBIAN-CVE-2022-46176](https://patchblox.com/security/data/fix/linux/debian-cve-2022-46176.md) | Jan 11, 2023 | | Linux | rust-debugger-common amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-debuginfo amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-debugsource amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-doc amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-gdb amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-lldb amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-src amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-std-static amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-std-static-wasm32-unknown-unknown amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rust-std-static-wasm32-wasi amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rustfmt amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | | Linux | rustfmt-debuginfo amzn 2023 | 1.66.1-1.amzn2023.0.3 | [ALAS2023-2023-109](https://patchblox.com/security/data/fix/linux/alas2023-2023-109.md) | Feb 17, 2023 | --- Data as of 2026-11-08T06:59:42Z UTC.
