**Name of the Vulnerable Software and Affected Versions** react/http versions prior to 1.9.0 **Description** The react/http HTTP server component contains a potential DoS vulnerability that can cause high CPU load when processing large HTTP request bodies. This vulnerability has little to no impact on the default configuration, but can be exploited when explicitly using the `RequestBodyBufferMiddleware` with very large settings. This might lead to consuming large amounts of CPU time for processing requests and significantly delay or slow down the processing of legitimate user requests. **Recommendations** To resolve the issue, upgrade to release 1.9.0 or later. As a temporary workaround, consider keeping the request body limited using `RequestBodyBufferMiddleware` with a sensible value. Alternatively, place a reverse proxy in front of the ReactPHP HTTP server to filter out any excessive HTTP request bodies.
