CyberRota Analysis
AI-GeneratedThe vulnerability affects the compression middleware in Node.js and Express applications prior to version 1.8.2, where aborted connections can lead to memory leaks in the zlib stream. This allows a remote unauthenticated attacker to exploit the issue by repeatedly initiating requests and disconnecting, potentially exhausting server memory and causing crashes. Organizations using this middleware should prioritize upgrading to version 1.8.2 or later to mitigate the risk of denial-of-service attacks.

Original NVD Description
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.
