A fix is available — apply it.

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 _safe_filename 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.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
