From 13.4.6 to before 15.5.16 and 16.2.5, React Server Component responses can be vulnerable to cache poisoning in deployments that rely on shared caches with insufficient response partitioning. In affected conditions, collisions in the _rsc cache-busting value can allow an attacker to poison cache entries so users receive the wrong response variant for a given URL. This vulnerability is fixed in 15.5.16 and 16.2.5.","state":0,"publishedAt":"2026-05-13T18:16:19.037+00:00","modifiedAt":"2026-10-26T14:10:00.13+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","score":3.7,"severity":"LOW"}],"references":["https://github.com/vercel/next.js/security/advisories/GHSA-vfv6-92ff-j949"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-44582","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-328"],"productCriteria":["cpe:2.3:a:vercel:next.js:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-05-13T18:16:19.037","lastModified":"2026-10-26T14:10:00.130"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
