Oh My Posh is the most customisable and low-latency cross platform/shell prompt renderer. Prior to 29.35.1, write(s rune) in src/terminal/writer.go emitted attacker-controlled current directory names and Git metadata, including Commit.Subject, Commit.Author.Name, Commit.Author.Email, and RawUpstreamURL, without removing C0/C1 terminal control characters such as ESC, BEL, CSI, and OSC, allowing terminal escape sequence injection during prompt rendering that could overwrite the clipboard, spoof the prompt or screen, manipulate the window title, or disrupt the terminal. This issue is fixed in version 29.35.1.

Oh My Posh versions prior to 29.35.1 allow terminal escape sequence injection via unsanitized prompt segment data. This occurs because dynamic strings such as directory names and Git commit metadata are rendered into the prompt without neutralizing raw terminal control characters. An attacker controlling these values can inject ANSI/OSC escape sequences that the victim's terminal executes on every prompt render, enabling clipboard hijacking, prompt spoofing, window-title manipulation, and denial of service.
