According to its self-reported version number, the Atlassian Confluence application running on the remote host is prior to 9.2.23 or 9.3.x prior to 10.2.15. It is, therefore, affected by multiple vulnerabilities, including flaws in bundled third-party dependencies :

- An injection vulnerability in the bundled minimist dependency. (CVE-2021-44906)

- A security misconfiguration vulnerability in the bundled Bouncy Castle dependency. (CVE-2025-14813)

- Multiple denial of service vulnerabilities in the bundled node-tar dependency. (CVE-2026-59873, CVE-2026-59874, CVE-2026-59871)

- A man-in-the-middle vulnerability in the bundled Apache Tomcat dependency. (CVE-2026-53434)

- Multiple denial of service vulnerabilities in the bundled linkify-it dependency. (CVE-2026-48801, CVE-2026-59887)

- A SQL injection vulnerability in the bundled Hibernate ORM dependency. (CVE-2026-0603)

- A file inclusion vulnerability in the bundled node-tar dependency. (CVE-2026-29786)

- A man-in-the-middle vulnerability in the bundled PostgreSQL JDBC Driver dependency. (CVE-2026-54291)

- A denial of service vulnerability in the bundled underscore dependency. (CVE-2026-27601)

- A denial of service vulnerability in the bundled PostgreSQL JDBC Driver dependency. (CVE-2026-42198)

- An information disclosure vulnerability in the bundled postcss dependency. (CVE-2026-45623)

- A denial of service vulnerability in the bundled Micrometer dependency. (CVE-2026-40983)

- A denial of service vulnerability in the bundled axios dependency. (CVE-2026-25639)

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:

  - linkify-it is a links recognition library with full Unicode support. Prior to 5.0.2, the mailto: schema
    validator used by .test() and .match() can be invoked at every mailto: occurrence and scan the remaining
    input through src_email_name in lib/re.mjs, causing O(n^2) CPU consumption on crafted user text. This
    issue is fixed in version 5.0.2. (CVE-2026-59887)

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-7c23b06d74 advisory.

    Security release: `LinkifyIt.match()` was quadratic on untrusted input when linkify is enabled     ([GHSA-8m2q-wq3r-6hq8](https://github.com/tsutsu3/linkify-it-py/security/advisories/GHSA-8m2q-wq3r-6hq8)).

    - Fix quadratic complexity in `LinkifyIt.match()`, port of linkify-it 5.0.1 and 5.0.2 (upstream     [CVE-2026-48801](https://github.com/advisories/GHSA-22p9-wv53-3rq4),     [CVE-2026-59887](https://github.com/advisories/GHSA-v245-v573-v5vm))     ([#82](https://github.com/tsutsu3/linkify-it-py/pull/82))
    - Match validators at a position instead of slicing the tail, needed because Python 3.10 does not optimize     the `^` anchor ([#82](https://github.com/tsutsu3/linkify-it-py/pull/82))
    - Allow `;` in the email name, matching linkify-it. **Behavior change**: `a;b@example.com` is now     linkified ([#82](https://github.com/tsutsu3/linkify-it-py/pull/82))
    - Update port.yml (linkify-it v5.0.2) ([#82](https://github.com/tsutsu3/linkify-it-py/pull/82))
