CVE-2026-40588

blueprintUE is a tool to help Unreal Engine developers.

Impact

blueprintUE is a tool to help Unreal Engine developers. 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's existing password before accepting a new one. Any attacker who obtains a valid authenticated session — through XSS exploitation, session sidejacking over HTTP, physical access to a logged-in browser, or a stolen "remember me" cookie — can immediately change the account password without knowing the original credential, resulting in permanent account takeover. This vulnerability is fixed in 4.2.0.
