Echo: nanoid: security update to 3.3.6+echo.2

high Tenable Self-Hosted Container Security Plugin ID 461181

Description

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

 - nanoid is a secure, URL-friendly, unique string ID generator for JavaScript. Prior to versions 3.3.12 and
 5.1.11, the nanoid(size) function in index.js and index.cjs coerces the user-influenced size parameter to
 a signed 32-bit integer, allowing a value of 2147483648 to become -2147483648 and corrupt the process-wide
 CSPRNG poolOffset in fillPool(), which causes subsequent session tokens, CSRF tokens, API keys, and unique
 identifiers to become the deterministic string "uuuuuuuuuuuuuuuuuuuuu" until the process restarts. This
 issue is fixed in versions 3.3.12 and 5.1.11. (CVE-2026-73086)

Solution

Update the nanoid library and its related packages to version 3.3.6+echo.2 or later.
