Cargo between 1.68 and 1.96 incorrectly normalized the URLs of third-party registries using the sparse index protocol. If a hosting provider allowed multiple registries to be hosted with arbitrary names within the same domain, an attacker able to publish crates in a registry could obtain the credentials of others users of the same registry. The severity of the vulnerability is **low**, due to the extremely niche requirements needed to achieve the attack.

The remote Fedora 45 host has packages installed that are affected by a vulnerability as referenced in the FEDORA-2026-67365d8467 advisory.

    - Update cargo-c to version 0.10.24 (plus dependency updates).
    - Initial packaging of the anstyle-hyperlink, anstyle-progress, and cargo-util-terminal crates.

Tenable has extracted the preceding description block directly from the Fedora security advisory.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1872 advisory.

    gitoxide is an implementation of git written in Rust. Prior to 0.21.1, a malicious tree can be constructed     that will, when checked out with gitoxide, permit writing an attacker-controlled symlink into any existing     directory the user has write access to. During checkout, all symlink index entries are deferred and     created after regular files using a single shared gix_worktree::Stack. Internally, this uses a     gix_fs::Stack. gix_fs::Stack::make_relative_path_current() caches validated path prefixes: when the     previously-processed leaf component exactly matches the leading component(s) of the next path, the leaf-     to-directory transition at gix-fs/src/stack.rs invokes only delegate.push_directory(), never     delegate.push(). In gix_worktree::stack::delegate::StackDelegate, when the state member is     State::CreateDirectoryAndAttributesStack, Attributes::push_directory() only loads attributes (from the     ODB, in the clone case), and does not perform any other checks. The on-disk symlink_metadata() check and     unlink-on-collision live in StackDelegate::push()'s invocation of create_leading_directory(), which is     therefore bypassed for the cached prefix. The final symlink is created with plain     std::os::unix::fs::symlink, which follows symlinks in parent directories. Therefore, it's possible to     provide a tree with duplicate symlink and directory entries that exploits this. This vulnerability is     fixed in 0.21.1. (CVE-2026-44471)

If a hosting provider allowed multiple registries to be hosted with arbitrary names within     the same domain, an attacker able to publish crates in a registry could obtain the credentials of others     users of the same registry.

    A security vulnerability has been detected in libssh2 up to 1.11.1. The impacted element is the function     userauth_password of the file src/userauth.c. Such manipulation of the argument username_len/password_len     leads to integer overflow. The attack may be launched remotely. The name of the patch is     256d04b60d80bf1190e96b0ad1e91b2174d744b1. A patch should be applied to remediate this issue.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Cargo between 1.68 and 1.96 incorrectly normalized the URLs of third-party registries using the sparse
    index protocol. If a hosting provider allowed multiple registries to be hosted with arbitrary names within
    the same domain, an attacker able to publish crates in a registry could obtain the credentials of others
    users of the same registry. The severity of the vulnerability is **low**, due to the extremely niche
    requirements needed to achieve the attack. (CVE-2026-5222)

  - Cargo incorrectly handled symlinks inside of crate tarballs downloaded from third-party registries,
    allowing a malicious crate to override the source code of another crate from the same registry. The
    severity of the vulnerability is **medium** for users of third-party registries. Users of crates.io are
    **not affected**, as crates.io forbids uploading crates containing any symlink. (CVE-2026-5223)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Cargo between 1.68 and 1.96 incorrectly normalized the URLs of third-party registries using the sparse     index protocol. If a hosting provider allowed multiple registries to be hosted with arbitrary names within     the same domain, an attacker able to publish crates in a registry could obtain the credentials of others     users of the same registry. The severity of the vulnerability is **low**, due to the extremely niche     requirements needed to achieve the attack. (CVE-2026-5222)

Note that Nessus relies on the presence of the package as reported by the vendor.
