Reachability Analysis

This vulnerability is potentially reachable

learning-opentok-node-0.0.0/app.js (Application)
  -> morgan-1.10.0/index.js (Extension)
   -> ❌ on-headers-1.0.2/index.js (Vulnerable Component)

Vulnerability Details

on-headers is a node.js middleware for listening to when a response writes headers. A bug in on-headers versions "<1.1.0" may result in response headers being inadvertently modified when an array is passed to "response.writeHead()". Users should upgrade to version 1.1.0 to receive a patch. Uses are strongly encouraged to upgrade to "1.1.0", but this issue can be worked around by passing an object to "response.writeHead()" rather than an array.
Mend Note: The description of this vulnerability differs from MITRE.

CVE-2026-5078

Vulnerable Library - morgan-1.10.0.tgz

HTTP request logger middleware for node.js

Library home page: https://registry.npmjs.org/morgan/-/morgan-1.10.0.tgz

Path to dependency file: /package.json

Path to vulnerable library: /package.json

Dependency Hierarchy:

• ❌ morgan-1.10.0.tgz (Vulnerable Library)

Found in base branch: main

Vulnerability Details

Impact: The morgan logging middleware's :remote-user token extracts the Basic auth username from the Authorization request header and writes it to the log stream without neutralizing control characters. An unauthenticated attacker can send a crafted Authorization Basic header containing CR or LF bytes to inject forged log lines, breaking the one-request-per-line structure of access logs and enabling log forgery against downstream log consumers. The built-in combined, common, default, and short formats are affected, as well as any custom format that references :remote-user. Affected versions: morgan 1.2.0 through 1.10.1. Patches: upgrade to morgan 1.11.0, which neutralizes control characters in the :remote-user token output. Workarounds: use a custom format string that does not include :remote-user.
