The formatter in Mix.Tasks.UsageRules.SearchDocs interpolated those publisher-controlled fields verbatim, neutralizing no terminal control characters; the only transform it applied adds escape sequences rather than removing them. A malicious package can embed ANSI terminal escape sequences (cursor movement, line erase, carriage returns, OSC 52 clipboard writes) in its indexed documentation, so when a developer runs a search that surfaces those docs the sequences reach the terminal unchanged \u2014 forging the displayed hexdocs URL or a suggested command, hiding text, or writing to the clipboard. No authentication or privileged position is required; only publishing a package.\n\nThis issue affects usage_rules: from 0.1.18 before 1.2.8."}], "lastModified": "2026-09-08T15:18:49.987", "sourceIdentifier": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db"}
