Reflected cross-site scripting in multiple admin modules

Multiple admin modules in UpdraftPlus did not properly escape output before rendering in HTML. This could allow attackers to inject malicious scripts via crafted

input or error responses, potentially leading to script execution in the administrator’s browser.
