js-yaml is a JavaScript YAML parser and dumper. In js-yaml before 4.1.1 and 3.14.2, it's possible for an attacker to modify the prototype of the result of a parsed yaml document via prototype pollution (`__proto__`). All users who parse untrusted yaml documents may be impacted. The problem is patched in js-yaml 4.1.1 and 3.14.2. Users can protect against this kind of attack on the server by using `node --disable-proto=delete` or `deno` (in Deno, pollution protection is on by default).

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0978 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-68429:
    Storybook is a frontend workshop for building user interface components and pages in isolation. A     vulnerability present starting in versions 7.0.0 and prior to versions 7.6.21, 8.6.15, 9.1.17, and 10.1.10     relates to Storybooks handling of environment variables defined in a `.env` file, which could, in     specific circumstances, lead to those variables being unexpectedly bundled into the artifacts created by     the `storybook build` command. When a built Storybook is published to the web, the bundles source is     viewable, thus potentially exposing those variables to anyone with access. For a project to potentially be     vulnerable to this issue, it must build the Storybook (i.e. run `storybook build` directly or indirectly)     in a directory that contains a `.env` file (including variants like `.env.local`) and publish the built     Storybook to the web. Storybooks built without a `.env` file at build time are not affected, including     common CI-based builds where secrets are provided via platform environment variables rather than `.env`     files. Storybook runtime environments (i.e. `storybook dev`) are not affected. Deployed applications that     share a repo with your Storybook are not affected. Users should upgrade their Storybookon both their     local machines and CI environmentto version .6.21, 8.6.15, 9.1.17, or 10.1.10 as soon as possible.
    Maintainers additionally recommend that users audit for any sensitive secrets provided via `.env` files     and rotate those keys. Some projects may have been relying on the undocumented behavior at the heart of     this issue and will need to change how they reference environment variables after this update. If a     project can no longer read necessary environmental variable values, either prefix the variables with     `STORYBOOK_` or use the `env` property in Storybooks configuration to manually specify values. In     either case, do not include sensitive secrets as they will be included in the built bundle.

    CVE-2025-64718:
    js-yaml is a JavaScript YAML parser and dumper. In js-yaml 4.1.0 and below, it's possible for an attacker     to modify the prototype of the result of a parsed yaml document via prototype pollution (`__proto__`). All     users who parse untrusted yaml documents may be impacted. The problem is patched in js-yaml 4.1.1. Users     can protect against this kind of attack on the server by using `node --disable-proto=delete` or `deno` (in     Deno, pollution protection is on by default).

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - js-yaml is a JavaScript YAML parser and dumper. In js-yaml before 4.1.1 and 3.14.2, it's possible for an
    attacker to modify the prototype of the result of a parsed yaml document via prototype pollution
    (`__proto__`). All users who parse untrusted yaml documents may be impacted. The problem is patched in js-
    yaml 4.1.1 and 3.14.2. Users can protect against this kind of attack on the server by using `node
    --disable-proto=delete` or `deno` (in Deno, pollution protection is on by default). (CVE-2025-64718)

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

  - js-yaml is a JavaScript YAML parser and dumper. In js-yaml before 4.1.1 and 3.14.2, it's possible for an     attacker to modify the prototype of the result of a parsed yaml document via prototype pollution     (`__proto__`). All users who parse untrusted yaml documents may be impacted. The problem is patched in js-     yaml 4.1.1 and 3.14.2. Users can protect against this kind of attack on the server by using `node
    --disable-proto=delete` or `deno` (in Deno, pollution protection is on by default). (CVE-2025-64718)

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