0 CVE-2026-105297 is a high-severity vulnerability in Cloudflare's Pingora HTTP/2 server before version 0.8.1. The issue arises from the server using default h2 crate limits without explicit application limits on decoded header-list size and concurrent streams. This allows a remote unauthenticated attacker to cause excessive memory allocation by sending crafted HTTP/2 header references, potentially leading to denial of service via out-of-memory termination. Cloudflare CDN customers are not affected as their internal Pingora services do not use HTTP/2 clients. The vulnerability is fixed in Pingora version 0.8.1, which enforces stricter limits by default.
