    Missing Release of Resource after Effective Lifetime

    @libp2p/circuit-relay-v2 is an Implementation of Circuit Relay v2

    Affected versions of this package are vulnerable to Missing Release of Resource after Effective Lifetime through the reserve() path in packages/transport-circuit-relay-v2/src/server/reservation-store.ts. An attacker can grow memory usage and eventually trigger an out-of-memory failure by repeatedly sending valid RESERVE refresh requests for the same relay reservation. The reservation store reuses the same abort signal when a reservation is refreshed, but it still registers a new abort listener on each successful refresh. A peer that can reserve on a public relay can keep one reservation entry alive while accumulating unbounded listeners and closure state, causing sustained heap growth and service degradation.

    How to fix Missing Release of Resource after Effective Lifetime?

    Upgrade @libp2p/circuit-relay-v2 to version 4.2.9 or higher.
