{"id":"CVE-2026-64821","summary":"djangoSIGE 1.10 CSRF via GET-based Order Cancellation Views","details":"djangoSIGE through 1.10 (commit a6fe7e8) contains a cross-site request forgery vulnerability that allows unauthenticated attackers to cancel sales or purchase orders on behalf of authenticated users by exploiting order-cancellation logic implemented inside HTTP GET method handlers in CancelarOrcamentoVendaView, CancelarPedidoVendaView, CancelarOrcamentoCompraView, and CancelarPedidoCompraView. Attackers can lure an authenticated victim with change_orcamentovenda or equivalent permissions to a page containing a cross-origin reference such as an img tag pointing to the cancellation endpoint, bypassing CSRF token validation entirely since Django's CsrfViewMiddleware only enforces CSRF checks on unsafe HTTP methods.","modified":"2026-10-08T02:51:33.080225111Z","published":"2026-07-21T20:31:35.885Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-352"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64821.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"last_affected":"1.10"}]}]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64821.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64821"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/djangosige-csrf-via-get-based-order-cancellation-views"},{"type":"REPORT","url":"https://github.com/thiagopena/djangoSIGE/pull/163"},{"type":"PACKAGE","url":"https://github.com/thiagopena/djangoSIGE"},{"type":"EVIDENCE","url":"https://github.com/americooo/pentest-writeups/tree/main/djangoSIGE-CVE-2026-64821-64822"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/thiagopena/djangoSIGE","events":[{"introduced":"0"},{"last_affected":"a6fe7e8e3a7d52ba0a25305df4e5e7e0cd5f5792"}]}],"versions":["0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64821.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
