CVE-2026-80430Network attack vectorHinoki check available

Arbitrary file creation via staged symlink following

Published Sep 25, 2026 · Updated Sep 25, 2026

Improper link resolution in kitty 0.47.0 through 0.48.2 allows context-dependent attackers to create files outside drag staging. The subdir_data_for_drag() path builder opens a concatenated descendant path after ignoring an EEXIST result, so a same-name symlink and directory redirect add_payload() outside the staged tree. Reachability requires a client program to send the crafted drag item sequence; creation is limited to new files and directories at locations writable by the kitty user.
