Security release for Backdrop CMS. This release fixes 1 security vulnerability:
Other than this one security fix, no other changes have been made. Site owners are encouraged to update to Backdrop 1.35.1 instead of this release if possible, as it also addresses a vulnerability in CKEditor 5 that cannot be easily back-ported to the 1.34.x releases.
Notes for updating
No changes have been made to the .htaccess, robots.txt or default settings.php files in this release. Updating customized versions of those files is not necessary.
The database update script does not need to be run.
