Linux Distros Unpatched Vulnerability : CVE-2026-104827

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - react/http is an event-driven, streaming HTTP client and server implementation for ReactPHP. From 1.0.0 until 1.11.1, React\Http\Browser uses...

react/http: Unbounded HTTP Client Response Header Buffering Leads to Memory Exhaustion DoS

Summary React\Http\Browser and its lower-level HTTP stack impose no limit on the size of a response's header section while it is being received. ClientRequestStream::handleData appends every incoming byte to an internal buffer and only scans that buffer for the \r\n\r\n or \n\n terminator, withou...

ReactPHP react/http DoS

The vulnerability of the handleData function in the ReactPHP library’s react/http package, which handles streaming HTTP messages, is related to the execution of a loop with an unreachable exit condition. Exploiting this vulnerability could allow a remote attacker to cause a service failure...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop via the ChunkedDecoder::handleData process. An attacker can cause the process to enter an infinite loop and exhaust CPU resources by sending a malformed HTTP message with Transfer-Encoding: chunked that exploits specific...

PT-2026-93758

Name of the Vulnerable Software and Affected Versions react/http versions 0.6.0 through 1.11.0 Description A denial of service issue exists where a malformed HTTP message using Transfer-Encoding: chunked can cause the ReactHttpIoChunkedDecoder to enter an infinite loop. This occurs because 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: 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: Uncontrolled Recursion

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. ...

Uncontrolled Recursion

Overview @nestjs/microservices is a Nest - modern, fast, powerful node.js web framework @microservices Affected versions of this package are vulnerable to Uncontrolled Recursion through the handleData function in packages/microservices/helpers/json-socket.ts. An attacker can crash the TCP...

Go crypto/tls HandleData Buffer Overflow DoS

The vulnerability of the HandleData function in the crypto/tls package for the Go programming language is related to an incorrect limitation on data size before buffering. Exploiting this vulnerability could allow a remote attacker to cause a service failure...
