Summary
libp2p is a JavaScript implementation of the libp2p networking stack. Prior to version 4.2.9, the reservation refresh path in reservation-store.ts reuses the same retimeableSignal but unconditionally registers another abort listener on every refresh. As a result, a remote peer can repeatedly send valid RESERVE requests for the same reservation, causing unbounded listener and closure growth in @libp2p/circuit-relay-v2 relay servers and leading to denial of service. This issue is fixed in version 4.2.9.

Summary
libp2p is a JavaScript Implementation of libp2p networking stack. Prior to 16.0.0, @libp2p/gossipsub defaultDecodeRpcLimits set maxIhaveMessageIDs and maxIwantMessageIDs to Infinity, allowing oversized IHAVE and IWANT control message arrays in message/decodeRpc.ts and gossipsub.ts to synchronously iterate roughly 180,000 message IDs per 4 MB frame and block the Node.js event loop. This issue is fixed in version 16.0.0.

Summary
libp2p is a JavaScript Implementation of libp2p networking stack. Prior to version 16.2.6, an unauthenticated remote peer can exhaust the disk storage of any @libp2p/kad-dht node running in server mode by sending an unbounded stream of PUT_VALUE messages whose keys bypass all content validation. No credentials, no prior relationship, and no protocol deviation beyond a crafted key are required. The victim node's datastore fills until the host disk is exhausted, making the node unavailable. This issue has been patched in version 16.2.6.

CWE
- CWE-400 - Uncontrolled Resource Consumption
Summary
js-libp2p is the official javascript Implementation of libp2p networking stack. Versions older than `v0.38.0` of js-libp2p are vulnerable to targeted resource exhaustion attacks. These attacks target libp2p’s connection, stream, peer, and memory management. An attacker can cause the allocation of large amounts of memory, ultimately leading to the process getting killed by the host’s operating system. While a connection manager tasked with keeping the number of connections within manageable limits has been part of js-libp2p, this component was designed to handle the regular churn of peers, not a targeted resource exhaustion attack. Users are advised to update their js-libp2p dependency to `v0.38.0` or greater. There are no known workarounds for this vulnerability.

"value": "js-libp2p is the official javascript Implementation of libp2p networking stack. Versions older than `v0.38.0` of js-libp2p are vulnerable to targeted resource exhaustion attacks. These attacks target libp2p\u2019s connection, stream, peer, and memory management. An attacker can cause the allocation of large amounts of memory, ultimately leading to the process getting killed by the host\u2019s operating system. While a connection manager tasked with keeping the number of connections within manageable limits has been part of js-libp2p, this component was designed to handle the regular churn of peers, not a targeted resource exhaustion attack. Users are advised to update their js-libp2p dependency to `v0.38.0` or greater. There are no known workarounds for this vulnerability."
