Summary
App::Ack versions through 3.10.0 for Perl print unsanitised terminal escape sequences from filenames in several output modes
Details

App::Ack versions through 3.10.0 for Perl print unsanitised terminal escape sequences from filenames in several output modes.

When ack prints a filename whose basename contains terminal control bytes such as ANSI escape sequences, those bytes reach the terminal unchanged. Version 3.10.0 added a safefilename helper that sanitises the filenames printed by -f, -g, the colored match heading, and per-match lines, but the --show-types, -l/-L, and -c paths still emit the raw filename.

A file whose name embeds cursor-movement or color escapes can overwrite or recolor earlier terminal output, or be passed unchanged to a downstream consumer.
