rulesync is vulnerable to Prototype Pollution

Medium Risk
This Affects:
rulesyncTL;DR
An improper input validation issue in rulesync Gemini CLI policy conversion allowed crafted permission rules to trigger prototype pollution through reserved JavaScript object keys, bypass JSON field-boundary matching through unsafe glob-to-regex translation, or create unintended match-all shell permissions through empty or wildcard bash patterns. This could enable attackers controlling policy files to corrupt permission state, weaken access restrictions, or silently grant overly broad command execution rights.
