CVE-2026-93749 source-map-js through 1.2.1 Event Loop Denial of Service

source-map-js through 1.2.1 fails to validate the per-section offset line value in indexed source maps, allowing attackers to specify arbitrary numeric values. Attackers can supply extremely large offset line values that cause synchronous event loop blocking for extended periods, preventing the...

CVE-2026-69184 c-ares: CPU-exhaustion denial of service via unbounded DNS name compression pointer chains

c-ares is an asynchronous resolver library. Prior to 1.34.7, aresdnsnameparse enforces backward DNS compression pointers but does not bound the total pointer hops or assembled name length. A malicious DNS server can send a response containing a long descending pointer chain and many resource...

libp2p is a JavaScript implementation of the libp2p networking stack. Prior to 11.0.26, @libp2p/floodsub accepts unauthenticated RPC frames on /floodsub/1.0.0 through PeerStreams.attachInboundStream in packages/floodsub/src/peer-streams.ts without protobuf element limits, then processRpc and...

GHSA-RW4J-R22C-9GC3 AsyncSSH: asyncio event-loop freeze via SSH maximum packet size = 0 in SSH_MSG_CHANNEL_OPEN / OPEN_CONFIRMATION

Summary A malicious SSH server can wedge an AsyncSSH client, and an authenticated client can wedge an AsyncSSH server, by sending a channel maximum packet size of 0 in SSHMSGCHANNELOPENCONFIRMATION server→client or SSHMSGCHANNELOPEN client→server. AsyncSSH stores the peer-supplied value verbatim...

CVE-2026-92596

A flaw was found in Nodemailer's addressparser component. This vulnerability, due to quadratic time complexity, allows a remote attacker to cause a Denial of Service DoS. By sending a specially crafted email with a large, comma-separated list of addresses, the attacker can block the Node.js event...

unbound: Unbound: Denial of Service via continuous queries on TCP/DoT connection

A flaw was found in Unbound. A malicious actor can exploit a vulnerability in the TCP/DoT reading procedure, which lacks a limit on consecutive reads. By continuously streaming distinct uncached names over a TCP/DoT connection, an attacker can monopolize a worker's event loop. This can lead to a...

CVE-2026-92596 Nodemailer before 9.1.0 Denial of Service via addressparser

Nodemailer before 9.1.0 contains a quadratic time complexity vulnerability in the addressparser component that allows remote attackers to cause denial of service by supplying a crafted comma-separated address list. Attackers can send a single email with a large number of addresses to block the...

CVE-2026-92596 Nodemailer before 9.1.0 Denial of Service via addressparser

Nodemailer before 9.1.0 contains a quadratic time complexity vulnerability in the addressparser component that allows remote attackers to cause denial of service by supplying a crafted comma-separated address list. Attackers can send a single email with a large number of addresses to block the...

CVE-2026-62949

A flaw was found in AsyncSSH, a Python package for SSHv2 protocol implementation. A malicious SSH server or an authenticated client can exploit this vulnerability by sending a specially crafted SSH packet with a zero-sized maximum packet size. This can cause the AsyncSSH event loop to freeze,...
