CVE-2026-31960

Description

A flaw was found in Quill. An attacker with the ability to intercept and modify network traffic, such as through a TLS-intercepting proxy or a compromised certificate authority, could send an arbitrarily large HTTP response body during the Apple notarization process. This unbounded read of the response body into memory would cause the Quill client to run out of memory and crash, leading to a Denial of Service (DoS) for the application.
