CVE-2026-44579 (GCVE-0-2026-44579)

Vulnerability from cvelistv5 – Published: 2026-05-13 17:04 – Updated: 2026-06-30 12:10

Title

Next.js: Denial of Service via connection exhaustion in applications using Cache Components

Summary

Next.js is a React framework for building full-stack web applications. From to before 15.5.16 and 16.2.5, applications using Partial Prerendering through the Cache Components feature can be vulnerable to connection exhaustion through crafted POST requests to a server action. In affected configurations, a malicious request can trigger a request-body handling deadlock that leaves connections open for an extended period, consuming file descriptors and server capacity until legitimate users are denied service. This vulnerability is fixed in 15.5.16 and 16.2.5.

GHSA-MG66-MRH9-M8JX

Vulnerability from github – Published: 2026-05-11 15:56 – Updated: 2026-05-14 20:38

Summary

Next.js vulnerable to Denial of Service via connection exhaustion in applications using Cache Components

Details

Impact

Applications using Partial Prerendering through the Cache Components feature can be vulnerable to connection exhaustion through crafted POST requests to a server action. In affected configurations, a malicious request can trigger a request-body handling deadlock that leaves connections open for an extended period, consuming file descriptors and server capacity until legitimate users are denied service.

Fix

We now treat the header used for resuming Partial Prerendered requests as an internal-only header and strip it from untrusted incoming requests. This header should never be accepted directly from external clients.

Workarounds

If you cannot upgrade immediately, block requests that would be handled by Next.js if they contain the Next-Resume header at the edge.

Severity

7.5 (High)
