description: "The Keybase browser extension fix for a query-string parsing differential: its parser now rejects duplicate parameter keys instead of silently keeping one, so a crafted link can no longer make the extension open a chat with a different user than the host page displays. The same commit escapes the dots in the regexes that decide which site a page belongs to."
