UpdraftPlus Premium 2.24.2.26

SECURITY: Fixed a missing nonce combined with a URL sanitisation failure, which could lead to a targetted XSS opportunity (if an attacker persuades a logged-in administrator to both re-authorise their connection to a remote storage (e.g. Dropbox) and then to follow a link personally crafted for their site before re-authorising whilst logged in, he can then store a fixed JavaScript payload in the WP admin area (they would need a further route to use that ability to cause any damage). Because of the need for the administrator to co-operate in multiple steps, this attack is very unlikely (but you should of course still update).
FIX: DigitalOcean S3-compatible storage does not work with disabled SSL entirely where possible settings.
FIX: If there was an error or network connectivity issue on first attempt of uploading a plugin/theme file, then the second attempt of uploading the same file would make the file become corrupted thus resulting in installation failure.
COMPATIBILITY: Suppress htmlspecialchars deprecation warnings on PHP 8.1
COMPATIBILITY: Suppress some PHP 8.2 deprecation notices from use of ${} style variables, and others from use of dynamic properties
TWEAK: Handle web hosting company setup that disabled pclose() but not popen()
