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...

CVE-2026-104827

The react/http library (an event-driven HTTP client and server for ReactPHP ) is vulnerable to a memory exhaustion Denial of Service (DoS) in versions 1.0.0 through 1.11.1 . The root cause lies in React\Http\Browser 's ClientRequestStream::handleData() function, which appends response-header byte...

PT-2026-115093

Name of the Vulnerable Software and Affected Versions react/http versions 1.0.0 through 1.11.0 Description ReactHttpBrowser fails to enforce a size limit on the internal buffer used to store response-header bytes. When the handleData function in ClientRequestStream receives data, it appends...

CVE-2026-104827: Allocation of Resources Without Limits or Throttling

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 ClientRequestStream::handleData to append response-header bytes to an internal buffer without enforcing a size limit. A remote server can send a valid stat...

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...

react/http: A malformed HTTP chunked body can lead to a denial-of-service and peg the CPU

Summary A malformed HTTP message using Transfer-Encoding: chunked can drive React\Http\Io\ChunkedDecoder into an infinite loop, pegging a CPU core and freezing the event loop. Because ReactPHP is single-threaded, one such message stalls the entire process for every client until it is killed. Both...

GHSA-X424-64QH-5J54 react/http: A malformed HTTP chunked body can lead to a denial-of-service and peg the CPU

Summary A malformed HTTP message using Transfer-Encoding: chunked can drive React\Http\Io\ChunkedDecoder into an infinite loop, pegging a CPU core and freezing the event loop. Because ReactPHP is single-threaded, one such message stalls the entire process for every client until it is killed. Both...

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...

CVE-2026-84997

react/http is an event-driven, streaming HTTP client and server implementation for ReactPHP. From 0.6.0 until 1.11.1, React\Http\Io\ChunkedDecoder could enter an infinite loop while processing a malformed Transfer-Encoding: chunked body because handleData required its buffer to shrink on every...

CVE-2026-84997

react/http (ReactPHP) is vulnerable to a denial-of-service via a malformed HTTP chunked body. The ChunkedDecoder enters an infinite loop when it receives either an incomplete terminal-chunk trailer without CRLF or exactly two non-CRLF bytes after a completed non-terminal chunk, because handleData...
