{"schema":"threatline.record/2","record":{"id":"CVE-2026-114606","aliases":["GHSA-fjgc-8xgj-rvh4"],"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.","categories":["Unclassified"],"product":"drawio-desktop","vendor":"jgraph","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114606","source_modified_at":"2026-10-22T16:35:34.251Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"drawio-desktop","vendor":"jgraph","versions":[{"version":"< 31.4.4","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":5.6,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00193,"percentile":0.08533,"score_date":"2026-10-23"},"published_at":"2026-10-22T16:35:34.251Z","modified_at":"2026-10-22T16:35:34.251Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-114606","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-22T16:35:34.251Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-114606","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/jgraph/drawio-desktop/security/advisories/GHSA-fjgc-8xgj-rvh4","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/jgraph/drawio-desktop/commit/9c933514b8bcc90a91d88c685525a8885de4027e","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/jgraph/drawio-desktop/releases/tag/v31.4.4","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-22T16:35:34.251Z","content_hash":"7e4e1753f8bc025375a04846e687372faff48c3a5244007ad32cde021a1974df"}}
