CVE-2026-33174: Activestorage Unbounded Byte Ranges Dos
Missing size limit validation for requested HTTP byte ranges can lead to memory exhaustion and Denial of Service (DoS). An attacker can request an unbounded range (e.g., `bytes=0-`) which gets fully loaded into memory. Validate the total aggregated size of the byte ranges before processing them.
