CVE-2026-7790 is a high-severity vulnerability in the ninenines cowlib library, specifically in the cow_http_te module's chunked transfer-encoding parser. The parser accepts an unbounded number of hexadecimal digits in the chunk-size field, leading to excessive CPU and memory consumption. An unauthenticated remote attacker can exploit this by sending a specially crafted HTTP/1.1 request with a very long chunk-size hex string, causing denial of service through resource exhaustion. This affects cowlib versions from 0.6.0 before 2.16.1. No official patch or remediation guidance is currently provided by the vendor.
