SCA: security update for react/http (GHSA-g4f2-2pf3-2pwj)

high Tenable Cloud Security Plugin ID 474726

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 status line and
 partial header, withhold the \r\n\r\n or \n\n header terminator, and continue streaming data so the buffer
 grows for the life of the connection. Applications that fetch attacker-controlled or attacker-influenced
 URLs, including URLs reached through redirects, can exhaust PHP memory_limit and crash the event-loop or
 worker process. Confidentiality and integrity are unaffected. This issue is fixed in version 1.11.1.
 (CVE-2026-104827)

Solution

Update the react/http library and its related packages to version 1.11.1 or later.
