| ## 2025-03-25 - [Broken Access Control via Placeholder Middleware] | ||
| **Vulnerability:** Authorization bypass due to "pass-through" placeholder middleware. | ||
| **Learning:** Security-critical routes in the Express API used stubbed middleware (`(req, res, next) => next()`) which effectively disabled all RBAC/ABAC checks, even though the routes were intended to be protected. | ||
| **Prevention:** Never use stubbed/placeholder middleware in production-facing security-critical code. Ensure all routes have actual, verified authorization checks implemented at the route level to provide defense-in-depth. |

Line 6 is missing the blank line after the heading, so markdownlint MD022 will keep flagging this block.

The access-control fix is still incomplete for other document endpoints.
This hardens create/update/delete, but Line 235 still writes comments without checking the caller can access that document, and Line 264 / Line 290 still return comments/version history by document_id alone. Those handlers need the same route-level auth plus a document-level authorization check before the SQL runs, otherwise the documents API still leaks or mutates data outside these three routes. As per coding guidelines, "Implement authentication middleware to verify JWT tokens on protected routes" and "Implement RBAC for user, admin, and moderator roles".

- Around line 42-49: The query currently binds CallExpr call and
DataFlow::SourceNode data independently, causing mismatches; update the
where-clause to require that the EHR source actually flows into an argument of
the transmission call by binding the call argument (e.g., argNode =
DataFlow::valueNode(call.getAnArgument())) and then require
data.flowsTo(argNode) before checking for encryption, and ensure the encryptCall
check uses that same argument node (replace
data.flowsTo(DataFlow::valueNode(encryptCall.getAnArgument())) with
argNode.flowsTo(...)/encryptCall.flowsFrom(argNode) as appropriate) so the
pattern enforces EHR source → call argument → optional encrypt → transmission.

CodeQL DataFlow SourceNode vs Node JavaScript TypeScript
💡 Result:
In CodeQL’s JavaScript/TypeScript data-flow libraries:
-
DataFlow::Nodeis the general type for nodes in the data-flow graph (expressions, certain declarations, etc.). It exposes low-level/local graph navigation likegetAPredecessor(),getASuccessor(), and can “work backwards” to origins viagetALocalSource(). [1][2] -
DataFlow::SourceNodeis a specialized subclass ofDataFlow::Noderepresenting nodes treated as origins for local flow tracking (for example: property reads, global references/this, parameters, calls, imports, object/function/class literals, etc.). It adds a convenience API (for examplegetAPropertyRead,getAPropertyReference,getACall,flowsTo(...)) that implicitly follows local flow and is designed for the common “start from a source and see where it goes” style of queries. [1][3]
Rule of thumb
- Use
DataFlow::SourceNodewhen you want to start from “source-like” constructs and use the fluent helpers (property reads/calls/member calls +flowsTo). [1][3] - Use
DataFlow::Nodewhen you want any node, need explicit edge-walking (getAPredecessor/getASuccessor), or want to find which sources reach a node (getALocalSource). [1][2]

CodeQL JavaScript data flow analysis flowsTo semantics
💡 Result:
In the CodeQL JavaScript/TypeScript libraries, DataFlow::SourceNode::flowsTo(sink) is a local (intra-procedural) reachability predicate:
- It holds when data originating at the source node can flow into
sinkin zero or more local steps (so it’s reflexive-transitive: the sourceflowsToitself, and also anything reachable through local flow edges). [1] - “Local” here means it uses only intra-procedural data flow (within a function). It does not do whole-program / inter-procedural tracking by itself (for that you use a global configuration and
MyFlow::flow(source, sink)). [2] - Practically, you use it like
arg.flowsTo(call.getArgument(0))to check whether a value derived fromargmay reach the argument expression. [2]

The query disconnects the transmitted data from its source, causing false positives.
The query at lines 42–49 binds data and call independently without requiring that data reaches any argument of call. This allows matching an unrelated EHR-looking variable alongside any transmission call in the same scope, producing false positives. For example, a patientPayload variable and a separate fetch() call in the same function would both match even if unrelated.
The fix is to bind the transmitted value explicitly to a call argument and verify the full data-flow chain: EHR source → call argument → (optionally encrypted) → transmission.

49, The query currently binds CallExpr call and DataFlow::SourceNode data
independently, causing mismatches; update the where-clause to require that the
EHR source actually flows into an argument of the transmission call by binding
the call argument (e.g., argNode = DataFlow::valueNode(call.getAnArgument()))
and then require data.flowsTo(argNode) before checking for encryption, and
ensure the encryptCall check uses that same argument node (replace
data.flowsTo(DataFlow::valueNode(encryptCall.getAnArgument())) with
argNode.flowsTo(...)/encryptCall.flowsFrom(argNode) as appropriate) so the
pattern enforces EHR source → call argument → optional encrypt → transmission.
- Fixed critical authorization bypass in documents API by replacing stubbed placeholder middleware with real RBAC/ABAC checks. - Modernized custom CodeQL queries to use the current module-based DataFlow API, resolving fatal errors in the CI pipeline. - Updated Sentinel journal with learnings from this task.

Bug: The requirePermissions and requireRoles middleware will always fail because the user object from authentication lacks the expected permissions and roles array properties.
Severity: CRITICAL
Suggested Fix
Update the authenticateRequest function in src/lib/auth/auth0-middleware.ts to correctly populate the user object. This should include fetching the user's permissions and roles (e.g., from Auth0's app_metadata) and attaching them as permissions: string[] and roles: string[] arrays to the user object.

valid.
Location: src/api/routes/documents.ts#L37
Potential issue: The authentication middleware populates the `req.user` object without a
`permissions` array and with a singular `role` string property instead of a `roles`
array. The `requirePermissions` and `requireRoles` middleware functions expect these
array properties to exist. Because `user.permissions` and `user.roles` are always
undefined, the authorization checks will always fail, returning a `403 Forbidden` error
for any user attempting to create, update, or delete documents. This effectively blocks
all write operations on the documents API.

Decouple the sink from the endpoint argument.
Line 68-Line 70 currently require the tainted value to land in the same argument that the EHR endpoint flows to. That misses the common case of fetch(url, { body }) / axios.post(url, data), where the endpoint is in one argument and the sensitive payload is in another. As written, this turns the new request sink into a false-negative for the main leak pattern.
Proposed fix
predicate isSink(DataFlow::Node sink) {
exists(DataFlow::CallNode call |
call.getCalleeName().matches("%log%") and
sink = call.getAnArgument()
)
or
exists(DataFlow::PropWrite write |

sink = write.getRhs()

🚨 Severity: HIGH
💡 Vulnerability: Broken access control via "pass-through" placeholder middleware.
🎯 Impact: Any user (or potentially unauthenticated requests if Astro integration fails) could create, update, or delete business documents, regardless of their roles or permissions.
🔧 Fix: Replaced stubbed
requirePermissionandrequireRolemiddleware with actual implementations fromsrc/api/middleware/auth.ts.✅ Verification: Created a local security test suite that confirmed 403 Forbidden is now correctly returned for unauthorized users and 201/200 is returned for authorized ones.
