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

  - Handlebars provides the power necessary to let users build semantic templates. In versions 4.0.0 through     4.7.8, the `@partial-block` special variable is stored in the template data context and is reachable and     mutable from within a template via helpers that accept arbitrary objects. When a helper overwrites     `@partial-block` with a crafted Handlebars AST, a subsequent invocation of `{{> @partial-block}}` compiles     and executes that AST, enabling arbitrary JavaScript execution on the server. Version 4.7.9 fixes the     issue. Some workarounds are available. First, use the runtime-only build     (`require('handlebars/runtime')`). The `compile()` method is absent, eliminating the vulnerable fallback     path. Second, audit registered helpers for any that write arbitrary values to context objects. Helpers     should treat context data as read-only. Third, avoid registering helpers from third-party packages (such     as `handlebars-helpers`) in contexts where templates or context data can be influenced by untrusted input.
    (CVE-2026-33938)

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