SCA: security update for parse-server (GHSA-38m6-82c8-4xfm)

high Tenable Cloud Security Plugin ID 442321

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js.
 Prior to versions 8.6.77 and 9.9.1-alpha.1, an unauthenticated attacker who knows a publicly-known Parse
 Application ID can submit a single HTTP request whose client SDK version field contains adversarial input
 that triggers polynomial backtracking in a request-header parser. The parsing runs before session
 authentication and before rate limiting on every /parse/* request, so the request consumes seconds to
 minutes of synchronous CPU on a Node.js worker before any access control evaluates it. A small number of
 concurrent requests can saturate a worker; a single large request via the body-field variant can pin a
 worker for minutes. Production deployments running the default configuration are affected. This issue has
 been patched in versions 8.6.77 and 9.9.1-alpha.1. (CVE-2026-47138)

Solution

Update the parse-server library and its related packages to version 8.6.77 or later.
