CVE-2026-54281 Nest: Middleware Bypass on Fastify via Trailing Slash

Nest is a framework for building scalable Node.js server-side applications. Prior to 11.1.24, an authentication bypass vulnerability exists in @nestjs/platform-fastify. When middleware is registered through NestJS's MiddlewareConsumer.forRoutes API on the Fastify adapter, an unauthenticated clien...

CVE-2026-49943: Stack-based Buffer Overflow

CZ.NIC BIRD Internet Routing Daemon through 2.19.0 contains a stack-based buffer overflow in the BGP ASPATH mask matching implementation in nest/a-path.c. The aspathmatch function uses a fixed-size stack array of 2048 + 1 pmpos entries, while parsepath expands ASPATH segments from a received BGP...

Unity Linux 20.1070e Security Update: mariadb (UTSA-2026-021671)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-021671 advisory. MariaDB before 10.7.2 allows an application crash because it does not recognize that SELECTLEX::nestlevel is local to each VIEW. Tenable has extracted the preceding...

Embedded Malicious Code

Overview Affected versions of this package are vulnerable to Embedded Malicious Code that conceals a credential-stealing payload and worm propagation logic. A malicious actor associated with the "TeamPCP" or "Mini Shai-Hulud" campaign compromised a maintainer's access token; this allowed the...

CVE-2026-40879

A flaw was found in Nest, a framework for building scalable Node.js server-side applications. A remote attacker can exploit this vulnerability by sending numerous small, valid JSON JavaScript Object Notation messages within a single TCP Transmission Control Protocol frame. This action causes the...

CVE-2026-40879

Nest is a framework for building scalable Node.js server-side applications. Prior to 11.1.19, when an attacker sends many small, valid JSON messages in one TCP frame, handleData recurses once per message; the buffer shrinks each call. maxBufferSize is never reached; call stack overflows instead. ...

CVE-2026-40879 Nest: DoS via Recursive handleData in JsonSocket (TCP Transport)

Nest is a framework for building scalable Node.js server-side applications. Prior to 11.1.19, when an attacker sends many small, valid JSON messages in one TCP frame, handleData recurses once per message; the buffer shrinks each call. maxBufferSize is never reached; call stack overflows instead. ...

CVE-2026-40879

Summary: Nest (Node.js) suffers a DoS via recursive handling of JSON frames over TCP. Before 11.1.19, handleData() recursed for each valid JSON message in a single frame, causing call stack growth and eventual RangeError when a ~47 KB payload is sent. This is fixed in 11.1.19. What’s affected: Th...

CVE-2026-35515

Nest is a framework for building scalable Node.js server-side applications. Prior to 11.1.18, SseStream.transform interpolates message.type and message.id directly into Server-Sent Events text protocol output without sanitizing newline characters \r, \n. Since the SSE protocol treats both \r and ...

CVE-2026-35515

NestJS/core (@nestjs/core) contains a vulnerability in SseStream._transform() where un sanitized interpolation of upstream data into SSE output allows an attacker to inject arbitrary SSE events, spoof event types, and corrupt reconnection state. The issue arises from inserting message.type and me...
