Common Weakness Enumeration

CWE-352

Weakness Allowed

Cross-Site Request Forgery

Abstraction: Compound · Status: Stable

The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.

Mapping guidance

This is a well-known Composite of multiple weaknesses that must all occur simultaneously, although it is attack-oriented in nature.

While attack-oriented composites are supported in CWE, they have not been a focus of research. There is a chance that future research or CWE scope clarifications will change or deprecate them. Perform root-cause analysis to determine if other weaknesses allow CSRF attacks to occur, and map to those weaknesses. For example, predictable CSRF tokens might allow bypass of CSRF protection mechanisms; if this occurs, they might be better characterized as randomness/predictability weaknesses.

Modes of introduction
Architecture and Design

REALIZATION: This weakness is caused during implementation of an architectural security tactic.

Detection methods

Manual Analysis

This weakness can be detected using tools and techniques that require manual (human) analysis, such as penetration testing, threat modeling, and interactive tools that allow the tester to record and modify an active session.

Specifically, manual analysis can be useful for finding this weakness, and for minimizing false positives assuming an understanding of business logic. However, it might not achieve desired code coverage within limited time constraints. For black-box analysis, if credentials are not known for privileged accounts, then the most security-critical portions of the application may not receive sufficient attention.

Consider using OWASP CSRFTester to identify potential issues and aid in manual analysis.

Effectiveness: High

These may be more effective than strictly automated techniques. This is especially the case with weaknesses that are related to design and business rules.

Automated Static Analysis

CSRF is currently difficult to detect reliably using automated techniques. This is because each application has its own implicit security policy that dictates which requests can be influenced by an outsider and automatically performed on behalf of a user, versus which requests require strong confidence that the user intends to make the request. For example, a keyword search of the public portion of a web site is typically expected to be encoded within a link that can be launched automatically when the user clicks on the link.

Effectiveness: Limited

Automated Static Analysis - Binary or Bytecode

According to SOAR [REF-1479], the following detection techniques may be useful:

Cost effective for partial coverage:

Bytecode Weakness Analysis - including disassembler + source code weakness analysis

Binary Weakness Analysis - including disassembler + source code weakness analysis

Effectiveness: SOAR Partial

Manual Static Analysis - Binary or Bytecode

According to SOAR [REF-1479], the following detection techniques may be useful:

Cost effective for partial coverage:

Notes

Relationship

There can be a close relationship between XSS and CSRF (CWE-352). An attacker might use CSRF in order to trick the victim into submitting requests to the server in which the requests contain an XSS payload. A well-known example of this was the Samy worm on MySpace [REF-956]. The worm used XSS to insert malicious HTML sequences into a user's profile and add the attacker as a MySpace friend. MySpace friends of that victim would then execute the payload to modify their own profiles, causing the worm to propagate exponentially. Since the victims did not intentionally insert the malicious script themselves, CSRF was a root cause.

Theoretical

The CSRF topology is multi-channel:

Attacker (as outsider) to intermediary (as user). The interaction point is either an external or internal channel.

Intermediary (as user) to server (as victim). The activation point is an internal channel.

Description

Summary

/ws/network/proxy is an admin-only WebSocket forward-proxy endpoint (target URL and headers fully attacker-specifiable via query parameters). Its websocket.Upgrader explicitly overrides CheckOrigin to unconditionally return true — disabling the origin validation that the gorilla/websocket library otherwise enforces by default. WebSocket handshake requests are not subject to CORS preflight at all (unlike fetch/XHR), so origin validation for WebSocket endpoints has to be done deliberately by the server; here it has been deliberately turned off instead. Combined with the endpoint's own query-parameter-driven proxy target, this is a textbook Cross-Site WebSocket Hijacking (CSWSH) primitive on a capability that amounts to an authenticated network pivot through the SiYuan kernel process.

Details

// kernel/api/network.go:501
upgrader := websocket.Upgrader{
    CheckOrigin: func(r *http.Request) bool { return true },
}
clientConn, upgradeErr := upgrader.Upgrade(c.Writer, c.Request, upgradeHeaders)

Route registration (admin-role-gated):

// kernel/api/router.go:614
ginServer.Handle("GET", "/ws/network/proxy", model.CheckAuth, model.CheckAdminRole, wsProxy)

The proxy target is fully attacker-controllable via query parameters, decoded and dialed directly:

// kernel/api/network.go:348
func parseForwardProxyParams(c *gin.Context) (parsedURL *url.URL, headers *http.Header, timeout time.Duration, err error) {
    uParam := c.Query("u")
    ...
    uBytes, decErr := base64.RawURLEncoding.DecodeString(uParam)
    ...
    parsedURL, err = url.ParseRequestURI(string(uBytes))
    ...
    hParam := c.Query("h")   // optional forwarded headers, also base64-encoded

A malicious webpage can construct, entirely from JavaScript with no special access:

new WebSocket("ws://127.0.0.1:6806/ws/network/proxy?u=" + base64url(attackerChosenTargetURL));

WebSocket handshake requests are GET requests carrying ambient cookies exactly like any other cross-site navigation, and are not covered by CORS preflight protections at all, this is a distinct attack surface from ordinary fetch/XHR-based CSRF, and easy to overlook precisely because the usual CORS mental model doesn't apply to it. Whether this is currently exploitable in a given browser depends on the same session-cookie SameSite configuration already covered by a separate report on this repository (no explicit SameSite is set on the session cookie), but even where that provides incidental protection today, the explicit CheckOrigin: func(r *http.Request) bool { return true } override removes a defense-in-depth layer that would otherwise exist automatically from the WebSocket library's own safe default, and is worth fixing independently of the cookie-attribute question.

Impact

If reachable (dependent on browser/cookie-attribute behavior at time of exploitation, as above), a malicious website visited by a user with an active, admin-privileged SiYuan session could open a WebSocket connection to this endpoint and direct the SiYuan kernel process to proxy arbitrary network traffic to an attacker-chosen target, effectively an authenticated SSRF/network-pivot primitive, using the victim's own machine and any network position it has (e.g., internal/localhost-only services on the victim's LAN that aren't reachable from the public internet), entirely via a drive-by visit to an unrelated website while SiYuan happens to be running.

PoC

No live browser PoC was run for this report, this is a code-level confirmation that the CheckOrigin override exists and unconditionally returns true, combined with tracing the fully attacker-controlled proxy-target construction. I also checked whether the other WebSocket-adjacent endpoints (/ws/plugin/rpc, /ws/broadcast) share this issue: they use a different WebSocket library (gws, not gorilla/websocket) with a different upgrade code path I have not independently verified for its own origin-checking defaults, flagging this as worth a follow-up check by your team rather than claiming it applies there too.

## Affected products

| Field | Value |
|---|---|
| Ecosystem | **Go** |
| Package name | `github.com/siyuan-note/siyuan/kernel` |
| Affected versions | `<= 3.7.3` (confirmed present in 3.7.3; maintainers should confirm lower bound) |
| Patched versions | *(none yet — leave blank until a fix is released)* |

## Severity

| Field | Value |
|---|---|
| Vector string | `CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:N/I:N/A:N` |
| Score | **5.5 (Medium)**, reflecting that real-world exploitability depends on the co-occurring session-cookie `SameSite` question (also separately reported) and requires a victim with an active admin session to visit an attacker-controlled page (`AC:H`, `UI:R`); I'd expect this to be scored higher by your team if you determine the cookie/browser-behavior precondition is reliably met, since the underlying capability (network pivot through the kernel process) is significant. |

## Weaknesses (CWE)

- **CWE-346** — Origin Validation Error (primary — this is the textbook CWE for CSWSH)
- **CWE-352** — Cross-Site Request Forgery (the broader category this specific WebSocket variant falls under)
- **CWE-918** — Server-Side Request Forgery (secondary — the resulting capability once a connection is hijacked)
-

Suggested Fix

Replace CheckOrigin: func(r *http.Request) bool { return true } with a real check — validate the Origin header against the expected local/loopback origin (or the configured workspace's own address), mirroring how IsLoopbackCallback-style validation is already done correctly elsewhere in this codebase (e.g. the MCP OAuth client's loopback-callback check). Also worth auditing the gws-based WebSocket endpoints (/ws/plugin/rpc, /ws/broadcast) for their own origin-validation defaults, since I did not verify those independently.

Whether this is currently exploitable in a given browser depends on the same session-cookie `SameSite` configuration already covered by a separate report on this repository (no explicit `SameSite` is set on the session cookie), but even where that provides incidental protection today, the explicit `CheckOrigin: func(r *http.Request) bool { return true }` override removes a defense-in-depth layer that would otherwise exist automatically from the WebSocket library\u0027s own safe default, and is worth fixing independently of the cookie-attribute question.\n\n### Impact\nIf reachable (dependent on browser/cookie-attribute behavior at time of exploitation, as above), a malicious website visited by a user with an active, admin-privileged SiYuan session could open a WebSocket connection to this endpoint and direct the SiYuan kernel process to proxy arbitrary network traffic to an attacker-chosen target, effectively an authenticated SSRF/network-pivot primitive, using the victim\u0027s own machine and any network position it has (e.g., internal/localhost-only services on the victim\u0027s LAN that aren\u0027t reachable from the public internet), entirely via a drive-by visit to an unrelated website while SiYuan happens to be running.\n\n### PoC\nNo live browser PoC was run for this report, this is a code-level confirmation that the `CheckOrigin` override exists and unconditionally returns `true`, combined with tracing the fully attacker-controlled proxy-target construction. I also checked whether the other WebSocket-adjacent endpoints (`/ws/plugin/rpc`, `/ws/broadcast`) share this issue: they use a different WebSocket library (`gws`, not `gorilla/websocket`) with a different upgrade code path I have not independently verified for its own origin-checking defaults, flagging this as worth a follow-up check by your team rather than claiming it applies there too.\n\n```\n## Affected products\n\n| Field | Value |\n|---|---|\n| Ecosystem | **Go** |\n| Package name | `github.com/siyuan-note/siyuan/kernel` |\n| Affected versions | `\u003c= 3.7.3` (confirmed present in 3.7.3; maintainers should confirm lower bound) |\n| Patched versions | *(none yet \u2014 leave blank until a fix is released)* |\n\n## Severity\n\n| Field | Value |\n|---|---|\n| Vector string | `CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:N/I:N/A:N` |\n| Score | **5.5 (Medium)**, reflecting that real-world exploitability depends on the co-occurring session-cookie `SameSite` question (also separately reported) and requires a victim with an active admin session to visit an attacker-controlled page (`AC:H`, `UI:R`); I\u0027d expect this to be scored higher by your team if you determine the cookie/browser-behavior precondition is reliably met, since the underlying capability (network pivot through the kernel process) is significant. |\n\n## Weaknesses (CWE)\n\n- **CWE-346** \u2014 Origin Validation Error (primary \u2014 this is the textbook CWE for CSWSH)\n- **CWE-352** \u2014 Cross-Site Request Forgery (the broader category this specific WebSocket variant falls under)\n- **CWE-918** \u2014 Server-Side Request Forgery (secondary \u2014 the resulting capability once a connection is hijacked)\n-\n```\n\n## Suggested Fix\nReplace `CheckOrigin: func(r *http.Request) bool { return true }` with a real check \u2014 validate the `Origin` header against the expected local/loopback origin (or the configured workspace\u0027s own address), mirroring how `IsLoopbackCallback`-style validation is already done correctly elsewhere in this codebase (e.g. the MCP OAuth client\u0027s loopback-callback check). Also worth auditing the `gws`-based WebSocket endpoints (`/ws/plugin/rpc`, `/ws/broadcast`) for their own origin-validation defaults, since I did not verify those independently.",

Mitigation MIT-4
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 [REF-1482].
  • For example, use anti-CSRF packages such as the OWASP CSRFGuard. [REF-330]
  • Another example is the ESAPI Session Management control, which includes a component for CSRF. [REF-45]
Mitigation
Implementation

Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.

Mitigation
Architecture and Design

Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330). [REF-332]

Mitigation
Architecture and Design

Identify especially dangerous operations. When the user performs a dangerous operation, send a separate confirmation request to ensure that the user intended to perform that operation.

Mitigation
Architecture and Design
  • Use the "double-submitted cookie" method as described by Felten and Zeller:
  • When a user visits a site, the site should generate a pseudorandom value and set it as a cookie on the user's machine. The site should require every form submission to include this value as a form value and also as a cookie value. When a POST request is sent to the site, the request should only be considered valid if the form value and the cookie value are the same.
  • Because of the same-origin policy, an attacker cannot read or modify the value stored in the cookie. To successfully submit a form on behalf of the user, the attacker would have to correctly guess the pseudorandom value. If the pseudorandom value is cryptographically strong, this will be prohibitively difficult.
  • This technique requires Javascript, so it may not work for browsers that have Javascript disabled. [REF-331]
Mitigation
Architecture and Design

Do not use the GET method for any request that triggers a state change.

Mitigation
Implementation

Check the HTTP Referer header to see if the request originated from an expected page. This could break legitimate functionality, because users or proxies may have disabled sending the Referer for privacy reasons.

CAPEC-111: JSON Hijacking (aka JavaScript Hijacking)

An attacker targets a system that uses JavaScript Object Notation (JSON) as a transport mechanism between the client and the server (common in Web 2.0 systems using AJAX) to steal possibly confidential information transmitted from the server back to the client inside the JSON object by taking advantage of the loophole in the browser's Same Origin Policy that does not prohibit JavaScript from one website to be included and executed in the context of another website.

CAPEC-462: Cross-Domain Search Timing

An attacker initiates cross domain HTTP / GET requests and times the server responses. The timing of these responses may leak important information on what is happening on the server. Browser's same origin policy prevents the attacker from directly reading the server responses (in the absence of any other weaknesses), but does not prevent the attacker from timing the responses to requests that the attacker issued cross domain.

CAPEC-467: Cross Site Identification

An attacker harvests identifying information about a victim via an active session that the victim's browser has with a social networking site. A victim may have the social networking site open in one tab or perhaps is simply using the "remember me" feature to keep their session with the social networking site active. An attacker induces a payload to execute in the victim's browser that transparently to the victim initiates a request to the social networking site (e.g., via available social network site APIs) to retrieve identifying information about a victim. While some of this information may be public, the attacker is able to harvest this information in context and may use it for further attacks on the user (e.g., spear phishing).

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.
