SCA: security update for morgan (GHSA-4vj7-5mj6-jm8m)

medium Tenable Cloud Security Plugin ID 444620

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-5078)

Solution

Update the morgan library and its related packages to version 1.11.0 or later.
