SCA: security update for next (GHSA-4633-3j49-mh5q)
medium Tenable Cloud Security Plugin ID 445134
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Next.js is a React framework for building full-stack web applications. In versions 12.0.0 through 15.5.20
and 16.0.0 through 16.2.10, a server-side fetch with a request body may return a cached response body from
a different request to the same URL but different body. Confidential data in the POST's response body
would then leak to unauthorized requests. Though the request itself will not be deduped. This is only an
issue when receiving request bodies with a content type charset other than UTF-8. For example, the UTF-16
byte sequences for 삃삃 and 섄섄 in the request body would share the same cache. This issue has been fixed in
versions 15.5.21 and 16.2.11. (CVE-2026-64647)
Solution
Update the next library and its related packages to version 15.5.21 or later.See Also
