CVE-2022-41322

Code execution via unsanitized notification identifier

Published Sep 23, 2022 · Updated Jun 1, 2025

Command injection in Kitty before 0.26.2 allows attackers to execute arbitrary code through a crafted desktop notification escape sequence. The notification parser accepts control characters in an attacker-supplied identifier, and report_notification_activated retransmits it over the TTY without sanitization. Exploitation requires displaying attacker-controlled terminal content and clicking its notification popup, after which injected input executes in the child session.
