{"id":"PYSEC-2026-4045","summary":"djust's Django model serialization has no sensitive-field denylist: password hashes, privilege flags, and PII on a public view attribute are sent to the client","details":"### Impact\nWhen a Django `Model` instance is assigned to a **public** view attribute, djust serialized it to the client with **no sensitive-field denylist** — sending fields such as `password` (the hash), privilege flags (e.g. `is_staff` / `is_superuser`), tokens, and other PII to the browser. Because exposing model objects to templates is a normal djust pattern, this could leak credentials/PII without the developer realizing the full object crossed the wire.\n\n### Patches\nFixed in **djust 1.0.7**. Model serialization applies a secure-by-default sensitive-field denylist (password/hash/token/secret-style fields and known privilege flags are withheld) with an identity-subset fallback.\n\n### Workarounds\nKeep `Model` instances on `_private` attributes and expose only the specific fields needed, until patched.","aliases":["CVE-2026-61588","GHSA-pvg3-6q9j-mj3x"],"modified":"2026-10-01T17:45:02.054819605Z","published":"2026-10-01T16:38:31.850987Z","references":[{"type":"WEB","url":"https://github.com/djust-org/djust/security/advisories/GHSA-pvg3-6q9j-mj3x"},{"type":"PACKAGE","url":"https://github.com/djust-org/djust"},{"type":"WEB","url":"https://github.com/djust-org/djust/releases/tag/v1.0.7"},{"type":"PACKAGE","url":"https://pypi.org/project/djust"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-pvg3-6q9j-mj3x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61588"}],"affected":[{"package":{"name":"djust","ecosystem":"PyPI","purl":"pkg:pypi/djust"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.7"}]}],"versions":["0.1.0","0.1.2","0.1.3","0.1.4","0.1.5","0.1.6","0.1.7","0.1.8","0.1.9","0.2.0","0.2.1","0.2.2","0.3.0","0.3.1","0.3.2","0.3.4","0.3.5","0.3.6","0.3.7","0.3.8","0.4.0","0.4.1","0.4.2","0.4.3","0.4.4","0.9.0","0.9.1","0.9.2","0.9.4","0.9.5","0.9.6","0.9.7","1.0.0","1.0.0rc11","1.0.1","1.0.2","1.0.3","1.0.4","1.0.5","1.0.6"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/djust/PYSEC-2026-4045.yaml"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
