Prior to 4.2.0, the password change form at /profile/{slug}/edit/ does not include a current_password field and does not verify the user\u0027s existing password before accepting a new one. Any attacker who obtains a valid authenticated session \u2014 through XSS exploitation, session sidejacking over HTTP, physical access to a logged-in browser, or a stolen \"remember me\" cookie \u2014 can immediately change the account password without knowing the original credential, resulting in permanent account takeover. This vulnerability is fixed in 4.2.0."
