CVE-2024-23746: 
Homebrew vulnerability analysis and mitigation

Miro Desktop 0.8.18 on macOS contains a vulnerability that allows local Electron code injection through a complex series of steps. The vulnerability was discovered in early 2024 and affects the Miro Desktop application specifically on macOS systems. The exploit involves bypassing a kTCCServiceSystemPolicyAppBundles requirement through a series of file manipulations including file copying, app.app/Contents renaming, asar modification, and renaming back to app.app/Contents (CVE Details, Miro About).

The vulnerability leverages specific aspects of Electron's security configuration and macOS system behavior. The attack requires a complex sequence of steps involving file system manipulations and modifications to the application's asar file. The exploit specifically targets the application's handling of content within the app.app/Contents directory and involves bypassing the kTCCServiceSystemPolicyAppBundles requirement (HackTricks Guide).

When successfully exploited, this vulnerability allows an attacker to inject and execute arbitrary code within the context of the Miro Desktop application. This is particularly significant because the injected code would run with the same permissions and access levels as the original application (Electron Blog).

Users should update to versions newer than 0.8.18 of Miro Desktop for macOS. For developers, the recommended mitigation involves properly configuring Electron's security features and fuses, particularly those related to code execution and content validation (Electron Blog).
