Description

CVE-2026-91043 is a high-severity vulnerability in the elixir-mint mint library affecting versions from 1.1.0 up to but not including 1.10.2. It involves improper resource allocation limits in the HTTP/2 client implementation, allowing a malicious HTTP/2 server to cause excessive memory consumption on the client by exploiting how header sizes are enforced. This can lead to denial of service by exhausting the memory of the process or the entire virtual machine.
