DOMPurify 3.1.3 through 3.3.1 and 2.5.3 through 2.5.8, fixed in commit 2726c74, contain a cross-site scripting vulnerability that allows attackers to bypass attribute sanitization by exploiting five missing rawtext elements (noscript, xmp, noembed, noframes, iframe) in the SAFE_FOR_XML regex. Attackers can include payloads like </noscript><img src=x onerror=alert(1)> in attribute values to execute JavaScript when sanitized output is placed inside these unprotected rawtext contexts.

The version of Primavera P6 Enterprise Project Portfolio Management installed on the remote host is affected by a vulnerability as referenced in the August 2026 CSPU advisory.

  - Vulnerability in the Primavera P6 Enterprise Project Portfolio Management product of Oracle Construction     and Engineering (component: Web Access (DOMPurify)). Supported versions that are affected are     21.12.0.0-21.12.21.8, 22.12.0.0-22.12.21.3, 23.12.0.0-23.12.19.0, 24.12.0.0-24.12.15.0 and     25.12.0.0-25.12.6.0. Easily exploitable vulnerability allows unauthenticated attacker with network     access via HTTP to compromise Primavera P6 Enterprise Project Portfolio Management. Successful attacks     require human interaction from a person other than the attacker and while the vulnerability is in     Primavera P6 Enterprise Project Portfolio Management, attacks may significantly impact additional     products (scope change). Successful attacks of this vulnerability can result in unauthorized access to     critical data or complete access to all Primavera P6 Enterprise Project Portfolio Management accessible     data as well as unauthorized update, insert or delete access to some of Primavera P6 Enterprise Project     Portfolio Management accessible data. (CVE-2026-41240)

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.
