According to its self-reported version number, the Atlassian Confluence application running on the remote host is prior to 9.2.22 or 9.3.x prior to 10.2.14. It is, therefore, affected by multiple vulnerabilities, including flaws in bundled third-party dependencies :

- Multiple server-side request forgery (SSRF) vulnerabilities in the bundled axios dependency. (CVE-2026-42043, CVE-2025-62718, CVE-2026-40175, CVE-2026-44492)

- A remote code execution vulnerability in the bundled lodash dependency. (CVE-2026-4800)

- A HTTP request smuggling vulnerability in the bundled Eclipse Jetty dependency. (CVE-2026-2332)

- A denial of service vulnerability in the bundled serialize-javascript dependency. (CVE-2026-34043)

- Multiple denial of service vulnerabilities in the bundled Netty dependency. (CVE-2026-42583, CVE-2026-42587)

- Multiple denial of service vulnerabilities in the bundled axios dependency. (CVE-2026-44496, CVE-2026-44488)

- A file inclusion vulnerability in the bundled fast-uri dependency. (CVE-2026-6321)

- An injection vulnerability in the bundled fast-uri dependency. (CVE-2026-6322)

- An injection vulnerability in the bundled js-cookie dependency. (CVE-2026-46625)

- A denial of service vulnerability in the bundled picomatch dependency. (CVE-2026-33671)

- A denial of service vulnerability. (CVE-2026-48779)

- A denial of service vulnerability in Atlassian Confluence. (CVE-2026-21577)

- A remote code execution vulnerability in the bundled axios dependency. (CVE-2026-44495)

- An injection vulnerability in the bundled logback dependency. (CVE-2025-11226)

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

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

  - ACE vulnerability in conditional configuration file processing by QOS.CH logback-core up to and including
    version 1.5.18 in Java applications, allows an attacker to execute arbitrary code by compromising an
    existing logback configuration file or by injecting an environment variable before program execution. A
    successful attack requires the presence of Janino library and Spring Framework to be present on the user's
    class path. In addition, the attacker must have write access to a configuration file. Alternatively, the
    attacker could inject a malicious environment variable pointing to a malicious configuration file. In both
    cases, the attack requires existing privilege. (CVE-2025-11226)

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

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

The remote openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2025:03456-1 advisory.

    - CVE-2025-11226: fixed the ACE vulnerability in conditional configuration file processing (bsc#1250715)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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