CVE-2026-54055

A flaw was found in Kitty, a cross-platform GPU-based terminal. A local attacker, specifically a child process running within the terminal, can exploit a Time-of-Check-Time-of-Use TOCTOU race condition in the file transmission protocol. This allows the attacker to create a symbolic link between a...

CVE-2026-54057

A flaw was found in Kitty, a cross-platform GPU-based terminal. An input sanitization vulnerability in Kitty's OSC 21 color-control query reply allows an attacker to inject controlled bytes, including newlines, directly into the shell's input. This could enable an attacker to execute arbitrary co...

CVE-2026-54056

A flaw was found in Kitty, a cross-platform GPU based terminal. A remote attacker can exploit a vulnerability in the kitten dnd feature by sending a specially crafted drag-and-drop request. This allows the attacker to overwrite or truncate arbitrary files on the local system that are writable by...

CVE-2026-42850

A flaw was found in Kitty, a cross-platform GPU based terminal. A remote attacker could exploit this vulnerability by sending a specially crafted escape code to a victim who is connected to the attacker via a program like netcat. This escape code triggers an unescaped error that is then executed ...

CVE-2026-42851

A flaw was found in Kitty, a cross-platform GPU-based terminal. A local attacker, or a remote attacker who can control output displayed in the terminal, could exploit this vulnerability. By sending specially crafted input to the terminal, the attacker can cause Kitty to execute arbitrary Python...

CVE-2026-54057

Kitty is a cross-platform GPU based terminal. In versions prior to 0.47.3, kitty's OSC 21 color-control query reply reflects attacker-controlled bytes, including newlines, into the shell's input without sanitization. Version 0.47.3 fixes the issue...

CVE-2026-54055

Kitty is a cross-platform GPU based terminal. In versions prior to 0.47.2, a local privilege escalation vulnerability exists in kitty's file transmission protocol where a child process running in the terminal can write to arbitrary files on the filesystem by exploiting a TOCTOU...

CVE-2026-42851

Kitty is a cross-platform GPU based terminal. In versions prior to 0.47.0, a program able to write bytes to a kitty terminal — a remote SSH peer, a downloaded file viewed with cat, a log line, an email body rendered in less, an issue body in a TUI, etc. — can cause kitty to execute...

CVE-2026-42850

Kitty is a cross-platform GPU based terminal. In versions prior to 0.47.0, it is possible to inject commands within the subshell through kitty error. A special escape code will make kitty return an error, this error is not escaped and will be correctly echoed back to the terminal with CRLF, as su...

Kitty is a cross-platform GPU based terminal. In versions prior to 0.47.3, kitty's OSC 21 color-control query reply reflects attacker-controlled bytes, including newlines, into the shell's input without sanitization. Version 0.47.3 fixes the issue...

CVE-2026-54057

Kitty (cross-platform GPU-based terminal) is affected in versions prior to 0.47.3. The issue arises in the OSC 21 (color-control) query reply, which may reflect attacker-controlled bytes—including newlines—into the shell input without sanitization. This can enable local command injection or input...
