What is CVE-2026-47114?

IINA Media Player versions prior to 1.4.3 expose a vulnerability that could allow remote attackers to exploit command execution. By crafting malicious URLs that utilize the iina://open custom URL scheme, attackers can inject unvalidated command parameters into the mpv runtime. This can result in the execution of arbitrary commands as the current macOS user once the browser protocol prompt is approved, enabling attackers to manipulate the system without the need for any valid media files. It is crucial for users to update to the latest version to mitigate this risk.
