Echo: compression: security update to 1.8.2

high Tenable Self-Hosted Container Security Plugin ID 473568

Description

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

 - compression is a Node.js and Express compression middleware. In versions before 1.8.2, when a client
 aborts the connection while a compressed response is still being sent, the zlib stream created to compress
 that response is never destroyed, so each aborted compressed response leaks its native zlib memory. A
 remote unauthenticated attacker can repeatedly open requests and disconnect early, exhausting the
 available memory and crashing the server. All applications using compression are affected. The issue is
 fixed in compression 1.8.2, and users should upgrade to 1.8.2 or later. (CVE-2026-87776)

Solution

Update the compression library and its related packages to version 1.8.2 or later.
