Answer in brief
CVE-2026-49147 records a High severity (CVSS 7.5) vulnerability in App::Ack versions through 3.10.0 for Perl print unsanitised terminal escape sequences from filenames in several output modes. The current sources do not mark it as known exploited. The current feed maps PETDANCE/App::Ack (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.5. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
