{"id":"CVE-2023-48705","aliases":["GHSA-cf9f-wmhp-v4pr","PYSEC-2023-285"],"url":"https://o3.security/vulnerability/CVE-2023-48705","summary":"nautobot has XSS potential in custom links, job buttons, and computed fields","details":"### Impact\n\nAll users of Nautobot versions earlier than 1.6.6 or 2.0.5 are potentially affected.\n\nDue to incorrect usage of Django's `mark_safe()` API when rendering certain types of user-authored content, including:\n\n- custom links\n- job buttons\n- computed fields\n\nit is possible that users with permission to create or edit these types of content could craft a malicious payload (such as JavaScript code) that would be executed when rendering pages containing this content.\n\n### Patches\n_Has the problem been patched? What versions should users upgrade to?_\n\nWe have fixed the incorrect uses of `mark_safe()` (generally by replacing them with appropriate use of `format_html()` instead) to prevent such malicious data from being executed.\n\nUsers on Nautobot 1.6.x LTM should upgrade to v1.6.6 and users on Nautobot 2.0.x should upgrade to v2.0.5.\n\n### Workarounds\n_Is there a way for users to fix or remediate the vulnerability without upgrading?_\n\nAppropriate object permissions can and should be applied to restrict which users are permitted to create or edit the aforementioned types of user-authored content. Other than that, there is no direct fix available.\n\n### References\n_Are there any links users can visit to find out more?_\n\n- https://github.com/nautobot/nautobot/pull/4832\n- https://github.com/nautobot/nautobot/pull/4833\n- https://docs.djangoproject.com/en/3.2/ref/utils/#django.utils.html.format_html\n- https://docs.djangoproject.com/en/3.2/ref/utils/#django.utils.safestring.mark_safe","published":"2023-11-22T15:15:06.189Z","modified":"2026-10-28T02:31:14.808448701Z","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:H/A:L"},"epss":{"score":0.00543,"percentile":0.43233,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"nautobot","fixedVersion":"1.6.6"},{"ecosystem":"PyPI","name":"nautobot","fixedVersion":"2.0.5"}],"fix":{"url":"https://github.com/nautobot/nautobot/commit/362850f5a94689a4c75e3188bf6de826c3b012b2","label":"nautobot/nautobot@362850f"},"references":[{"type":"WEB","url":"https://docs.djangoproject.com/en/3.2/ref/utils/#django.utils.html.format_html"},{"type":"WEB","url":"https://docs.djangoproject.com/en/3.2/ref/utils/#django.utils.safestring.mark_safe"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/48xxx/CVE-2023-48705.json"},{"type":"ADVISORY","url":"https://github.com/nautobot/nautobot/security/advisories/GHSA-cf9f-wmhp-v4pr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-48705"},{"type":"FIX","url":"https://github.com/nautobot/nautobot/commit/362850f5a94689a4c75e3188bf6de826c3b012b2"},{"type":"FIX","url":"https://github.com/nautobot/nautobot/commit/54abe23331b6c3d0d82bf1b028c679b1d200920d"},{"type":"FIX","url":"https://github.com/nautobot/nautobot/pull/4832"},{"type":"FIX","url":"https://github.com/nautobot/nautobot/pull/4833"},{"type":"PACKAGE","url":"https://github.com/nautobot/nautobot"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/nautobot/PYSEC-2023-285.yaml"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:31:14.808448701Z"}}
