{"id":"CVE-2026-88003","state":"PUBLISHED","title":"InvoicePlane: Failure to Revoke Administrative Privileges  After Role Downgrade","description":"InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2, InvoicePlane fails to revoke administrative privileges after a role downgrade because Admin_Controller trusts the user_type snapshot stored in an existing session instead of revalidating ip_users.user_type. When one administrator downgrades another account, the target's active session continues to authorize administrative requests. The downgraded user can use Users::form() to set user_type back to 1, restoring the database role and making the privilege escalation persistent. This vulnerability is fixed in 1.7.2.","publishedAt":"2026-09-25T21:20:13.236Z","updatedAt":"2026-09-28T13:04:37.691Z","severity":{"score":7.5,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["InvoicePlane InvoicePlane"],"affected":[{"vendor":"InvoicePlane","product":"InvoicePlane","versions":[{"version":"< 1.7.2","status":"affected"}]}],"references":["https://github.com/InvoicePlane/InvoicePlane/security/advisories/GHSA-25xj-pj36-wpp8","https://github.com/InvoicePlane/InvoicePlane/commit/904847f4e87b66fd6743cf9cc6f88b66c7fc3b81","https://github.com/InvoicePlane/InvoicePlane/commit/daa49ce3a50e0c93e01459b69c0d61bfc23d23eb","https://github.com/InvoicePlane/InvoicePlane/releases/tag/v1.7.2"],"weaknesses":["CWE-863"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/88xxx/CVE-2026-88003.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-88003","state":"PUBLISHED","datePublished":"2026-09-25T21:20:13.236Z","dateUpdated":"2026-09-28T13:04:37.691Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-09-09T19:19:27.406Z"},"containers":{"cna":{"title":"InvoicePlane: Failure to Revoke Administrative Privileges  After Role Downgrade","descriptions":[{"lang":"en","value":"InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments.
