{"id":"BIT-django-2026-15920","summary":"Potential cross-site scripting via URLField values in the admin","details":"An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8.\n`django.contrib.admin.utils.display_for_field()` renders `URLField` values as clickable links in the admin without validating the URL. A value stored with an unsafe scheme is displayed as a link on changelist and read-only admin pages, which allows cross-site scripting against staff users who click the link.\r\nExploitation requires the unsafe value to already be stored in the database. `URLField` validation through a `ModelForm` or the admin rejects unsafe schemes, so this affects applications that persist `URLField` data without running model validation, for example through direct queryset writes, deserialization, or bulk import of untrusted input.\nDjango would like to thank Egor Saltykov for reporting this issue.","aliases":["CVE-2026-15920"],"modified":"2026-09-08T08:46:37.020877521Z","published":"2026-08-18T10:04:42.641Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:djangoproject:django:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://docs.djangoproject.com/en/dev/releases/security/"},{"type":"FIX","url":"https://github.com/django/django/commit/13debb622a32720bda1bccda7622fd14fbf3931b"},{"type":"FIX","url":"https://github.com/django/django/commit/47511a21026cdd721d8fbf8571cc079bc38bb46d"},{"type":"FIX","url":"https://github.com/django/django/commit/5a260d309a4c8010c2ebda24eb758a5d95e2508a"},{"type":"FIX","url":"https://github.com/django/django/commit/b9adb81339cc418f8f56b1050cca6dfec3ab6349"},{"type":"DISCUSSION","url":"https://groups.google.com/g/django-announce"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-15920"},{"type":"ADVISORY","url":"https://www.djangoproject.com/weblog/2026/aug/04/security-releases/"}],"affected":[{"package":{"name":"django","ecosystem":"Bitnami","purl":"pkg:bitnami/django"},"ranges":[{"type":"SEMVER","events":[{"introduced":"5.2.0"},{"fixed":"5.2.17"},{"introduced":"6.0.0"},{"fixed":"6.0.8"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/django/BIT-django-2026-15920.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.0"}
