Summary

The Translate WordPress with Weglot 2.0 WordPress plugin before 6.4.3 does not escape the URLs it re-inserts into a page when rewriting links for a translated language, and reverses the encoding that was applied to them beforehand, allowing unauthenticated users to store a payload which executes in the browser of anyone viewing the page in a translated language.
