DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG. Versions prior to 3.4.0 have an inconsistency between FORBID_TAGS and FORBID_ATTR handling when function-based ADD_TAGS is used. Commit c361baa added an early exit for FORBID_ATTR at line 1214. The same fix was not applied to FORBID_TAGS. At line 1118-1123, when EXTRA_ELEMENT_HANDLING.tagCheck returns true, the short-circuit evaluation skips the FORBID_TAGS check entirely. This allows forbidden elements to survive sanitization with their attributes intact. Version 3.4.0 patches the issue.

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:34160 advisory.

    Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing     IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to     individual teams, while automation developers retain the freedom to write tasks that leverage existing     knowledge without the overhead. Ansible Automation Platform makes it possible for users across an     organization to share, vet, and manage automation content by means of a simple, powerful, and agentless     language.

    Security Fix(es):

    * automation-platform-ui: Axios: Denial of Service due to unenforced request and response size limits     (CVE-2026-44488)
    * automation-platform-ui: Axios: Information disclosure due to prototype pollution vulnerability     (CVE-2026-44495)
    * automation-platform-ui: fast-uri: URI authority bypass due to improper delimiter handling     (CVE-2026-6322)
    * automation-platform-ui: Axios: Arbitrary HTTP header injection via prototype pollution (CVE-2026-42035)
    * automation-platform-ui: DOMPurify: Cross-Site Scripting (XSS) via inconsistent tag sanitization     (CVE-2026-41240)
    * automation-platform-ui: protobufjs: Arbitrary code execution due to unsafe expression generation from     crafted protobuf descriptors (CVE-2026-44293)
    * python3.12-pyjwt: Authentication bypass due to forged JSON Web Tokens (CVE-2026-48526)
    * automation-controller: Dynaconf: Arbitrary code execution via Server-Side Template Injection     (CVE-2026-33154)
    * python3.12-urllib3: Information disclosure via cross-origin redirects forwarding sensitive headers     (CVE-2026-44431)
    * python3.12-urllib3: Denial of Service due to excessive HTTP response decompression (CVE-2026-44432)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-301cbbe347 advisory.

    This update contains upgrades to various npm packages used during the build to address CVEs, namely:

    - CVE-2025-69873 (ajv)
    - CVE-2026-0540 (DOMPurify)
    - CVE-2026-3449 (@tootallnate/once)
    - CVE-2026-4800 (lodash)
    - CVE-2026-6321 (fast-uri)
    - CVE-2026-41240 (DOMPurify)

    This is probably unimportant since these packages are used at build-time only.  They are not shipped with     python3-jupytext and therefore do not affect runtime.
