SCA: security update for morgan (GHSA-9f6g-j8ch-79g4)
medium Tenable Self-Hosted Container Security Plugin ID 448457
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- morgan is an HTTP request logger middleware for Node.js. In versions before 1.12.1, its escapeLogField()
function does not escape the double quote character, which delimits the quoted fields of the Apache
combined log format that morgan emits. An unauthenticated remote attacker who controls a value written to
a quoted field, such as the User-Agent or Referer header, can include a double quote to close that field
early, so a log consumer that parses the log by field position reads attacker-supplied text as the
following field. In the built-in formats this makes the recorded value differ from the value that was
sent, and in custom formats that quote an attacker-controlled token before a server-controlled one it can
forge values such as the response status. No newline is injected, so record separation stays intact. The
issue is fixed in morgan 1.12.1, which escapes the double quote. Users should upgrade to morgan 1.12.1 or
later. (CVE-2026-87859)
Solution
Update the morgan library and its related packages to version 1.12.1 or later.See Also
