A flaw was found in onefetch. An attacker can manipulate terminal output by embedding control characters and escape sequences into project manifest fields, such as the project name or version. When a user runs onefetch in an untrusted repository, these unsanitized values are printed directly to the screen, which can alter displayed content, modify window titles, obscure text, or trigger unexpected terminal emulator actions.
