{"cve":"CVE-2026-55485","nvd":{"published":"2026-08-28T20:18:27.657","modified":"2026-09-09T21:09:13.080","status":"Deferred","description":"Piccolo Admin is an admin interface and content management system for Python, built on top of Piccolo. Prior to 1.14.0, piccolo_admin/endpoints.py uses superuser_validators to block PUT, PATCH, DELETE, and POST requests by non-superusers but permits GET requests to configured user and session tables, while piccolo_api/session_auth/tables.py exposes SessionsBase.token because the token column is not secret. In deployments that add the Sessions and User tables to create_admin, a non-superuser administrator can call GET /api/tables/sessions/, obtain another user's live session token, replay it as the Cookie id value to impersonate a superuser, and permanently set superuser to true on the attacker's own row. This issue is fixed in version 1.14.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-200","CWE-269","CWE-863"],"references":["https://github.com/piccolo-orm/piccolo_admin/commit/96ddae12baf12288056cbb0cda6f9e8d7e22c86d","https://github.com/piccolo-orm/piccolo_admin/releases/tag/1.14.0","https://github.com/piccolo-orm/piccolo_admin/security/advisories/GHSA-2gh4-jmwq-rr8w","https://github.com/piccolo-orm/piccolo_api/commit/520ec2567ae1d2cc417c8c0d1ad0ddc05549a8a4","https://github.com/piccolo-orm/piccolo_api/pull/331"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-55485","score":0.00564,"percentile":0.46907,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2gh4-jmwq-rr8w","url":"https://osv.dev/vulnerability/GHSA-2gh4-jmwq-rr8w","summary":"piccolo-admin has a privilege escalation issue - admin to superuser via session-token disclosure in GET /api/tables/sessions/.","modified":"2026-09-10T12:25:39.426417744Z","packages":[{"ecosystem":"PyPI","name":"piccolo-admin","purl":"pkg:pypi/piccolo-admin","ranges":["<1.14.0"],"fixed":["1.14.0"]}]},{"id":"PYSEC-2026-3882","url":"https://osv.dev/vulnerability/PYSEC-2026-3882","summary":"piccolo-admin has a privilege escalation issue - admin to superuser via session-token disclosure in GET /api/tables/sessions/.","modified":"2026-09-10T12:15:10.891932988Z","packages":[{"ecosystem":"PyPI","name":"piccolo-admin","purl":"pkg:pypi/piccolo-admin","ranges":["<1.14.0"],"fixed":["1.14.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
