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

  - ammonia is a Rust library for repairing and securing untrusted HTML. Prior to 3.3.2, 4.0.2, and 4.1.3,     applications that explicitly allow the math tag, annotation-xml, and at least one raw-text HTML element     while disallowing the encoding attribute can permit mutation cross-site scripting. ammonia does not     correctly implement annotation-xml's encoding-dependent MathML integration-point behavior after attribute     filtering removes encoding, so the sanitizer validates a descendant under one namespace interpretation     while the browser reparses the output under another. An attacker can use that namespace transition and an     allowed raw-text HTML element to execute JavaScript when a user renders the sanitized output. The required     tags are not enabled by default, so applications that do not explicitly allow them are not affected. This     issue is fixed in versions 3.3.2, 4.0.2, and 4.1.3. (CVE-2026-63430)

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