What is CVE-2024-56803?
CVE-2024-56803 is a medium-severity code injection vulnerability in ghostty-org ghostty, published on 31 Dec 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
Ghostty is a cross-platform terminal emulator. Ghostty, as allowed by default in 1.0.0, allows attackers to modify the window title via a certain character escape sequence and then insert it back to the command line in the user's terminal, e.g. when the user views a file containing the malicious sequence, which could allow the attacker to execute arbitrary commands. This attack requires an attacker to send malicious escape sequences followed by convincing the user to physically press the "enter" key. Fixed in Ghostty v1.0.1.
Weakness: CWE-94
