{"id":"CVE-2026-57510","summary":"SuperPlane \u003c 0.27.0 Broken Object Level Authorization via CanvasService gRPC","details":"SuperPlane before 0.27.0 contains a broken object-level authorization vulnerability in the CanvasService gRPC handlers that allows authenticated users with viewer-level access to one organization to access resources belonging to other organizations by supplying arbitrary canvas or queue UUIDs without organization scoping. Attackers can read cross-tenant execution history and event payloads containing sensitive secrets, write queue items and canvas events into victim organizations, delete arbitrary canvases, and disrupt automation workflows across tenant boundaries.","modified":"2026-07-30T04:03:25.080743386Z","published":"2026-07-28T19:06:14.550Z","database_specific":{"cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57510.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57510.json"},{"type":"ADVISORY","url":"https://github.com/superplanehq/superplane/releases/tag/v0.27.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57510"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/superplane-broken-object-level-authorization-via-canvasservice-grpc"},{"type":"REPORT","url":"https://github.com/superplanehq/superplane/pull/5635"},{"type":"FIX","url":"https://github.com/superplanehq/superplane/commit/3e45cf4f1b5f1be9fbbfd90c97960a73f00f897b"},{"type":"PACKAGE","url":"https://github.com/superplanehq/superplane"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/superplanehq/superplane","events":[{"introduced":"0"},{"fixed":"a20345a6cff747f29620e0475385a56074a875b6"},{"fixed":"3e45cf4f1b5f1be9fbbfd90c97960a73f00f897b"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.27.0"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v0.26.0","v0.25.1","v0.25.0","v0.24.0","v0.23.0","v0.22.0","v0.21.0","v0.20.0","v0.19.0","v0.18.0","v0.17.0","v0.16.0","v0.15.0","v0.14.0","v0.13.0","v0.12.0","v0.11.0","v0.10.0","v0.9.0","v0.8.0","v0.7.0","v0.6.0","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.1.6","v0.1.5","v0.1.4","v0.1.3","v0.1.2","v0.1.1","v0.1.0","v0.0.47","v0.0.46","v0.0.45","v0.0.44","v0.0.43","v0.0.42","v0.0.41","v0.0.40","v0.0.39","v0.0.38","v0.0.37","v0.0.36","v0.0.35","v0.0.34","v0.0.33","v0.0.32","v0.0.31","v0.0.30","v0.0.29","v0.0.28","v0.0.27","v0.0.26","v0.0.25","v0.0.24","v0.0.23","v0.0.22","v0.0.21","v0.0.20","v0.0.19","v0.0.18","v0.0.17","v0.0.16","v0.0.15","v0.0.14","v0.0.12","v0.0.11","v0.0.10","v0.0.9","v0.0.8","v0.0.7","v0.0.6","v0.0.5","v0.0.4","v0.0.3","v0.0.2","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-57510.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
