{"id":"CVE-2026-55485","summary":"Piccolo Admin: Privilege escalation - admin to superuser via session-token disclosure in GET /api/tables/sessions/.","details":"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.","aliases":["GHSA-2gh4-jmwq-rr8w"],"modified":"2026-08-30T03:46:54.068750118Z","published":"2026-08-28T18:13:23.605Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55485.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-200","CWE-269","CWE-863"]},"references":[{"type":"WEB","url":"https://github.com/piccolo-orm/piccolo_admin/releases/tag/1.14.0"},{"type":"WEB","url":"https://github.com/piccolo-orm/piccolo_api/releases/tag/1.10.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55485.json"},{"type":"ADVISORY","url":"https://github.com/piccolo-orm/piccolo_admin/security/advisories/GHSA-2gh4-jmwq-rr8w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55485"},{"type":"FIX","url":"https://github.com/piccolo-orm/piccolo_admin/commit/96ddae12baf12288056cbb0cda6f9e8d7e22c86d"},{"type":"FIX","url":"https://github.com/piccolo-orm/piccolo_api/commit/520ec2567ae1d2cc417c8c0d1ad0ddc05549a8a4"},{"type":"FIX","url":"https://github.com/piccolo-orm/piccolo_api/pull/331"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/piccolo-orm/piccolo_admin","events":[{"introduced":"0"},{"fixed":"96ddae12baf12288056cbb0cda6f9e8d7e22c86d"},{"fixed":"d6053adc9f6d2db49cba9bcce97914ac3b2b989a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.14.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}},{"type":"GIT","repo":"https://github.com/piccolo-orm/piccolo_api","events":[{"introduced":"0"},{"fixed":"520ec2567ae1d2cc417c8c0d1ad0ddc05549a8a4"},{"fixed":"db250a319c36ac44fef67266f9b83f5b2d7fbb89"}],"database_specific":{"source":"REFERENCES"}}],"versions":["1.13.0","1.12.0","1.11.0","1.10.0","1.9.1","1.9.0","1.8.2","1.8.1","1.8.0","1.7.1","1.7.0","1.6.0","1.5.0","1.4.0","1.3.3","1.3.2","1.3.1","1.3.0","1.2.2","1.2.1","1.2.0","1.1.3","1.1.2","1.1.1","1.1.0","1.0.0","0.58.0","0.57.0","0.56.0","0.55.0","0.54.0","0.53.0","0.52.0","0.51.0","0.50.0","0.49.0","0.48.0","0.47.0","0.46.0","0.45.2","0.45.1","0.45.0","0.44.0","0.43.0","0.42.0","0.41.0","0.40.0","0.39.0","0.38.0","0.37.0","0.36.0","0.35.0","0.34.0","0.33.1","0.33.0","0.32.0","0.31.2","0.31.1","0.31.0","0.30.0","0.29.1","0.29.0","0.28.0","0.27.0","0.26.1","0.26.0","0.25.0","0.24.0","0.23.0","0.22.2","0.22.1","0.22.0","0.21.0","0.20.0","0.19.6","0.19.5","0.19.4","0.19.3","0.19.2","0.19.1","0.19.0","0.18.2","0.18.0","0.17.0","0.16.1","0.16.0","0.15.2","0.15.1","0.15.0","0.14.0","0.13.2","0.13.1","0.13.0","0.12.1","0.11.13","0.11.12","0.11.11","0.11.10","0.11.9","0.11.8","0.11.7","0.11.6","0.11.5","0.11.4","0.11.3","0.11.2","0.11.1","0.11.0","0.10.9","0.10.8","0.10.7","0.10.6","0.10.5","0.10.3","0.10.1","0.10.0","0.9.2","0.9.1","0.9.0","0.8.1","0.8.0","0.7.0","0.6.6","0.6.5","0.6.4","0.6.3","0.6.2","0.6.1","0.6.0","0.5.1","0.5.0","0.4.1","0.4.0","0.3.7","0.3.6","0.3.5","0.3.4","0.3.3","0.3.2","0.3.1","0.3.0","0.2.0","0.1.4","0.1.3","0.1.1","1.5.2","1.5.1","1.4.1","0.48.1","0.37.2","0.37.1","0.32.3","0.32.2","0.32.1","0.30.1","0.29.2","0.28.1","0.25.1","0.24.1","0.23.1","0.21.1","0.17.1","0.14.1","0.12.13","0.12.12","0.12.11","0.12.10","0.12.9","0.12.8","0.12.7","0.12.6","0.12.5","0.12.4","0.12.3","0.12.2","0.12.0","0.7.6","0.7.5","0.7.4","0.7.3","0.7.2","0.7.1","0.4.4","0.4.3","0.4.2","0.2.1","0.1.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55485.json"}}],"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:H/A:H"}]}
