Kitty is a cross-platform GPU based terminal. In versions 0.47.0 and 0.47.1, `kitten dnd` can allow a malicious remote drag-and-drop source to overwrite or truncate arbitrary files writable by the local kitty user. Remote `text/uri-list` drops are staged in a temporary directory, but on case-sensitive filesystems duplicate remote basenames are not de-duplicated. An attacker can first create a stag…

Koel is a free, open-source music streaming solution. Prior to version 9.3.5, Koel validates the podcast feed URL via the SafeUrl rule (DNS resolution + public IP check), but the individual episode values extracted from the RSS XML are stored directly into the database without any SSRF validation. When a user plays an episode, the server downloads the full HTTP response from …

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 such it will be run by the shell in use. To exploit this bug, the victim must use a netcat or a similar p…

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 attacker-supplied Python inside the running kitty process, with the user's full privileges. There is no approval …
