Hi,

The following vulnerability was published for node-compression.

CVE-2026-87776[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
