3.3.13

3.3.13 is a security release. It stops .etherpad imports from setting a pad's ownership, privacy or deletion token (GHSA-qq7c-m9pc-7q7v).

Import — .etherpad files can no longer change who owns a pad, make it public or plant a deletion token (GHSA-qq7c-m9pc-7q7v). Importing a .etherpad file into a pad with fewer than 10 revisions wrote every pad:<id>:* record in the file and every field of the pad record. Anyone who could edit a new pad could replace the creator's deletion token with their own, make a private group pad public, or name themselves as the pad's creator. Imports now only take the pad text, revisions and chat. The pad keeps its public status, pad-wide settings come from the file only when the creator imports it, and a file that names a different creator can only be imported by the pad's creator.
