How to Fix CVE-2023-26044
To remediate this vulnerability, upgrade all affected React/http dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Upgrade react/http to 1.9.0Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for react/httpHow to Check if You Are Affected
To determine whether your application is affected by CVE-2023-26044, inspect your project dependencies for React/http:
inspect dependencies for react/httpAnalyze the terminal output to locate any version of React/http in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.9.0), your application is affected.
Note: Verify declared build manifests and deployed runtime container environments.

"details" : "### Summary\n\nPrevious versions of ReactPHP's HTTP server component contain 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.\n\n### Patches\n\nThe supplied patch resolves this vulnerability for ReactPHP.\n\n### Workarounds\n\n- Keeping the request body limit using `RequestBodyBufferMiddleware` sensible will mitigate it.\n\n- Infrastructure or DevOps can place a reverse proxy in front of the ReactPHP HTTP server to filter out any excessive HTTP request bodies.\n\n### References\n\nA similar vulnerability was discovered in PHP recently, see also [PHP's security advisory](https://github.com/php/php-src/security/advisories/GHSA-54hq-v5wp-fqgv) (CVE-2023-0662).
