{"id":"CVE-2026-82911","state":"PUBLISHED","title":"CSRF in Prospero Flow CRM order confirmation allows unauthorized order state changes","description":"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.","publishedAt":"2026-09-04T15:33:44.562Z","updatedAt":"2026-09-04T19:31:33.575Z","severity":{"score":5.1,"label":"Medium","version":"4.0","vector":"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","source":"Secur0"},"assigner":"Secur0","products":["Roskus Prospero Flow CRM"],"affected":[{"vendor":"Roskus","product":"Prospero Flow CRM","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"5.15.11","versionType":"semver"}],"repo":"https://github.com/Roskus/prospero-flow-crm","modules":["Order"],"programFiles":["routes/module/order.php","resources/views/order/index.blade.php","app/Http/Controllers/Order/OrderConfirmController.php"],"cpes":["cpe:2.3:a:roskus:prospero_flow_crm:*:*:*:*:*:*:*:*"]}],"references":["https://github.com/Roskus/prospero-flow-crm/commit/a90c0c8c","https://secur0.com/en/cna/cve-list/cve-2026-82911-csrf-order-confirmation-prospero-flow-crm"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:13:15.269Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/82xxx/CVE-2026-82911.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-82911","state":"PUBLISHED","datePublished":"2026-09-04T15:33:44.562Z","dateUpdated":"2026-09-04T19:31:33.575Z","assignerShortName":"Secur0","assignerOrgId":"4daa8cea-433a-44bd-9456-53b127fc289a","dateReserved":"2026-08-31T10:22:08.667Z"},"containers":{"cna":{"title":"CSRF in Prospero Flow CRM order confirmation allows unauthorized order state changes","descriptions":[{"lang":"en","value":"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.
