{"id":"CVE-2026-114606","summary":"draw.io Desktop: Arbitrary local-file read via read-side IPC (no blessed-path gate)","details":"draw.io Desktop is the official Electron build of draw.io. Prior to 31.4.4, draw.io Desktop is vulnerable to arbitrary local-file disclosure through the Electron main process's read-side IPC handlers. The readFile, getFileDrafts, getBkpFile, fileStat, isFileWritable, checkFileExists, and watchFile actions operate on a renderer-chosen filesystem path with no blessed-path (assertWritablePath) authorization. The only gates are validateSender — a URL-prefix origin check — plus, for readFile alone, a content \"sniff\" and a lexical appBaseDir prefix block. The write-side handlers (saveFile, writeFile, saveDraft, deleteFile) are all protected by assertWritablePath; the read side is not. The result is a read/write authorization asymmetry: any frame executing in the app's file:// origin can read the contents of local files that the same origin is explicitly forbidden to write. This issue is fixed in version 31.4.4.","aliases":["GHSA-fjgc-8xgj-rvh4"],"modified":"2026-10-23T02:45:45.194890914Z","published":"2026-10-22T16:35:34.251Z","database_specific":{"cwe_ids":["CWE-200","CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114606.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114606.json"},{"type":"FIX","url":"https://github.com/jgraph/drawio-desktop/commit/9c933514b8bcc90a91d88c685525a8885de4027e"},{"type":"WEB","url":"https://github.com/jgraph/drawio-desktop/releases/tag/v31.4.4"},{"type":"ADVISORY","url":"https://github.com/jgraph/drawio-desktop/security/advisories/GHSA-fjgc-8xgj-rvh4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-114606"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jgraph/drawio-desktop","events":[{"introduced":"0"},{"fixed":"7bc3d0903103dc9c2115401736447676aa4a2ac3"},{"fixed":"9c933514b8bcc90a91d88c685525a8885de4027e"}],"database_specific":{"extracted_events":[{"strategy":"StringRangeExpression","range":[{"introduced":"0"},{"fixed":"31.4.4"}],"source":"AFFECTED_FIELD"},{"range":[{"fixed":"9c933514b8bcc90a91d88c685525a8885de4027e"}],"source":"REFERENCES_COMMIT"},{"original_tag":"v31.4.4","range":[{"fixed":"7bc3d0903103dc9c2115401736447676aa4a2ac3"}],"source":"REFERENCES_TAG"}]}}],"versions":["v31.3.1","v31.1.5","v30.3.14","v30.3.13","v30.3.6","v29.6.6","v20.2.6","v20.2.3","20.2.3","v19.0.3","v19.0.2","v19.0.0","v18.1.3","v18.0.6","v18.0.4","v18.0.1","v18.0.0","v17.5.0","v17.4.2","v17.2.4","v17.1.5","v16.5.1","v16.4.11","v16.3.0","v16.1.2","v16.0.2","v16.0.0","v15.8.7","v15.8.4","v15.7.3","v15.7.1","v15.4.0","v15.3.7","v15.3.5","v15.2.7","v15.2.6","v15.2.5","v15.1.3","v0.0.1","v15.1.1","v15.1.2","v14.9.6","v14.6.13","v14.6.11","v14.5.1","v14.4.3","v14.4.2","v14.4.0","v14.1.8","v14.1.5","v14.1.4","v14.1.3","v13.9.20","v13.10.0.2","v13.10.0.1","v13.10.0","v13.9.9","v13.9.8","v13.9.5","v13.7.9","v13.7.8","v13.7.3","v13.7.2","v13.6.2","v13.5.7","v13.5.1","v13.4.5","v13.4.4","v13.3.9","v13.3.5","v13.3.1","v13.2.5","v13.2.4","v13.2.2","v13.2.1","v13.0.3","v13.0.2","v13.0.1","v13.0.0","v12.9.13","v12.9.9","v12.9.3","v12.9.2","v12.6.5","v12.5.3","v12.4.2","v12.4.1","v12.4.0","v12.3.2","v12.2.2","v12.1.7","v12.1.4","v12.1.0","v11.3.0","v11.2.5","v11.2.4","v11.1.4","v11.1.1","v10.9.5","v10.8.0","v10.7.7","v10.6.5","v9.3.1","v8.8.0","v8.7.1","v8.6.5","v8.6.4","v8.4.7","v8.0.6","v7.9.5","v7.8.7","v7.8.4","v7.7.3","v7.7.2","v7.6.6","v7.5.5","v7.4.3","v7.3.5","v7.1.9","v7.1.6","v7.1.3","v7.1.2","v7.2.3","v7.2.1","v7.1.0","v7.0.8","v7.0.5","v7.0.4","v6.4.3","test6","test5","test4","test3","test2","test1","v6.3.1","v6.3.0","v6.2.9","v6.2.10"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-114606.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
