Is Passwork Auto Logon safe?

Low risk

Passwork Auto Logon lets any web page trigger cookie deletion for an arbitrary domain via an unchecked message handler.

The extension injects a content script into every http(s) page to auto-fill Passwork logins. That script forwards any page message beginning with 'pw_' to the background without checking the sender, so a web page can make it delete all cookies for a chosen domain or open a chosen URL in a new tab. The page cannot read the cookies back, but it can sign the user out of other sites.
