Summary

IINA before version 1.4.3 has a command execution vulnerability via the iina://open custom URL scheme. An attacker can supply a crafted URL with mpv_options/input-commands parameters that, after user approval in the browser, execute arbitrary commands on macOS.

Risk Assessment

An attacker can achieve remote code execution on the victim's machine with the privileges of the current macOS user, potentially leading to full system compromise.

Recommendation

Upgrade IINA to version 1.4.3 or later, and instruct users not to approve unknown iina:// protocol requests.

Original NVD description (English source)

IINA before 1.4.3 contains a user-assisted command execution vulnerability that allows remote attackers to execute arbitrary commands by supplying malicious mpv_-prefixed query parameters through the iina://open custom URL scheme handler. Attackers can deliver a crafted URL via a browser that passes unvalidated mpv_options/input-commands parameters into the mpv runtime, causing arbitrary command execution as the current macOS user upon approval of the browser protocol prompt without requiring a valid media file.
