    compression vulnerable to Denial of Service via memory leak on premature response close

    CVE-2026-87776 · GHSA-vc2v-76pw-4v95

    Affected
    • npm compression < 1.8.2
    Fixed in
    1.8.2· Vendor fix available
    Issue
    Impact A vulnerability in compression < 1.8.2 allows an attacker to trigger a Denial of Service (DoS) by disconnecting while a compressed response is being sent. When the client aborts the connection before the response finishes, the zlib stream created to compress that response is never destroyed, so each aborted compressed response leaks its native zlib memory. Repeated aborted requests can exhaust available memory. All applications using compression are affected. Patches Users should upgrade to 1.8.2. Workarounds None.

    Recommended action: Upgrade to 1.8.2 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
