Unauthenticated service hang via oversized multipart boundary
Published Mar 20, 2025 · Updated Oct 15, 2025
Uncontrolled resource consumption in Zylon PrivateGPT 0.5.0 allows remote attackers to hang the service via a crafted file upload. The multipart upload parser continuously processes an attacker-extended boundary suffix without a practical bound, consuming resources instead of rejecting the malformed delimiter. No authentication or user interaction is required; the resulting resource exhaustion makes the application API inaccessible for a prolonged period.
