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.","state":0,"publishedAt":"2026-05-13T18:16:18.123+00:00","modifiedAt":"2026-08-13T13:19:04.47+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"},{"system":"CVSS 3.1 · 0b0ca135-0b70-47e7-9f44-1890c2a1c46c · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/vercel/next.js/security/advisories/GHSA-mg66-mrh9-m8jx","https://access.redhat.com/errata/RHSA-2026:34608","https://access.redhat.com/errata/RHSA-2026:37272","https://access.redhat.com/errata/RHSA-2026:40974","https://access.redhat.com/errata/RHSA-2026:54435","https://access.redhat.com/security/cve/CVE-2026-44579","https://bugzilla.redhat.com/show_bug.cgi?id=2477193","https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-44579.json"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-44579","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-770","CWE-833"],"productCriteria":["cpe:2.3:a:vercel:next.js:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-05-13T18:16:18.123","lastModified":"2026-08-13T13:19:04.470"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
