SCA: security update for next (GHSA-5f7q-jpqc-wp7h)
high Tenable Cloud Security Plugin ID 437343
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- A denial of service vulnerability exists in Next.js versions with Partial Prerendering (PPR) enabled when
running in minimal mode. The PPR resume endpoint accepts unauthenticated POST requests with the `Next-
Resume: 1` header and processes attacker-controlled postponed state data. Two closely related
vulnerabilities allow an attacker to crash the server process through memory exhaustion: 1. **Unbounded
request body buffering**: The server buffers the entire POST request body into memory using
`Buffer.concat()` without enforcing any size limit, allowing arbitrarily large payloads to exhaust
available memory. 2. **Unbounded decompression (zipbomb)**: The resume data cache is decompressed using
`inflateSync()` without limiting the decompressed output size. A small compressed payload can expand to
hundreds of megabytes or gigabytes, causing memory exhaustion. Both attack vectors result in a fatal V8
out-of-memory error (`FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory`)
causing the Node.js process to terminate. The zipbomb variant is particularly dangerous as it can bypass
reverse proxy request size limits while still causing large memory allocation on the server. To be
affected you must have an application running with `experimental.ppr: true` or `cacheComponents: true`
configured along with the NEXT_PRIVATE_MINIMAL_MODE=1 environment variable. Strongly consider upgrading to
15.6.0-canary.61 or 16.1.5 to reduce risk and prevent availability issues in Next applications.
