What is CVE-2026-8468?

The Plug Project for Elixir is vulnerable to a Denial of Service attack due to improper resource allocation in its multipart header parsing. An unauthenticated attacker can exploit the flaw by sending a multipart/form-data request that lacks a complete header section, leading to unchecked memory accumulation as the server processes incoming request bytes. This vulnerability allows the attacker to exhaust server memory by making concurrent uploads, resulting in a complete service outage for users.

Affected Version(s)

plug 1.4.0 < 1.15.4

plug 1.16.0 < 1.16.3

plug 1.17.0 < 1.17.1
