Description

CVE-2026-80430 is a medium severity vulnerability in kitty versions 0.47.0 up to but not including 0.49.0. It involves improper link resolution before file access in the drag and drop protocol, allowing a local user to create files and directories outside the intended staging directory by exploiting symlink handling. The vulnerability arises because the code resolves paths by string construction rather than component-wise traversal, ignoring certain error conditions and not validating symlink targets. This can lead to arbitrary file and directory creation at any path writable by the user running kitty.
