CVE-2026-87776
NVD: compression is a Node.js and Express compression middleware. NVD: 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. NVD: A remote unauthenticated attacker can repeatedly open requests and disconnect early, exhausting the available memory and crashing the server.
