{"id":"CVE-2026-82911","summary":"CSRF in Prospero Flow CRM order confirmation allows unauthorized order state changes","details":"Cross-Site Request Forgery (CSRF) in the OrderConfirmController at GET /order/confirm/{order_number} in Roskus Prospero Flow CRM before 5.15.11 allows an unauthenticated attacker to confirm any order on behalf of an authenticated user by directing them to a crafted page. Laravel's VerifyCsrfToken middleware enforces CSRF tokens only on POST, PUT, PATCH, and DELETE requests; the Route::get declaration leaves this state-changing action unprotected. Session cookies configured with SameSite=Lax are automatically included in top-level cross-site navigation, so a single link click triggers OrderConfirmController::confirm() and transitions the target order from pending to confirmed without user authorization. Because order numbers are sequential integers, an attacker can enumerate and confirm all existing orders in a single automated sweep.","modified":"2026-10-28T02:30:37.298413438Z","published":"2026-09-04T15:33:44.562Z","database_specific":{"cna_assigner":"Secur0","cwe_ids":["CWE-352"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82911.json","unresolved_ranges":[{"extracted_events":[{"strategy":"StandardRange","range":[{"fixed":"5.15.11"}],"source":"AFFECTED_FIELD"}]},{"extracted_events":[{"range":[{"fixed":"5.15.11"}],"source":"CPE_FIELD","strategy":"CPEApplicability"}]},{"extracted_events":[{"range":[{"fixed":"5.15.11"}],"source":"DESCRIPTION"}]}]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82911.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-82911"},{"type":"ADVISORY","url":"https://secur0.com/en/cna/cve-list/cve-2026-82911-csrf-order-confirmation-prospero-flow-crm"},{"type":"FIX","url":"https://github.com/Roskus/prospero-flow-crm/commit/a90c0c8c"},{"type":"PACKAGE","url":"https://github.com/Roskus/prospero-flow-crm"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/roskus/prospero-flow-crm","events":[{"introduced":"0"},{"fixed":"a90c0c8c"}],"database_specific":{"extracted_events":[{"source":"REFERENCES_COMMIT","range":[{"fixed":"a90c0c8c"}]}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-82911.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
