Alpine: multiple cargo packages, multiple rust packages, multiple wasm-component-ld packages: security update to 1.91.1-r2

medium Tenable Cloud Security Plugin ID 442512

Description

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)

Solution

Update the cargo library and its related packages to version 1.91.1-r2 or later.
