Swift vulnerability analysis and mitigation

Overview

CVE-2025-0509 is a security vulnerability discovered in Sparkle before version 2.6.4. The vulnerability was disclosed in January 2025 and affects the Sparkle software update framework for macOS applications. The issue allows an attacker to replace an existing signed update with another payload, effectively bypassing Sparkle's (Ed)DSA signing checks (Sparkle Docs, CVE Details).

Technical details

The vulnerability has been assigned a CVSS score of 7.3 (High), with the vector CVSS:3.1/AV:A/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:H. The issue specifically affects the update verification process in Sparkle, where an attacker with access to the physical communication segment attached to the hardware can potentially bypass the (Ed)DSA signing verification mechanism (Oracle Advisory, Rapid7).

Impact

Successful exploitation of this vulnerability could result in the compromise of the update verification system, potentially allowing attackers to replace legitimate software updates with malicious payloads. This could lead to arbitrary code execution in the context of the affected application (NetApp Advisory).

Mitigation and workarounds

The vulnerability has been fixed in Sparkle version 2.6.4. Users and developers are strongly recommended to upgrade to this version or later. The fix has also been backported to version 1.27.3 for those using the older branch. Organizations should ensure their applications are updated to use the patched versions of Sparkle (Sparkle Docs, GitHub PR).
