wordpress developers reports:

Four security issues affect WordPress versions 5.3 and earlier; version 
5.3.1 fixes them, so youll want to upgrade. If you havent yet updated to 5.3,
there are also updated versions of 5.2 and earlier that fix the security 
issues. -Props to Daniel Bachhuber for finding an issue where an unprivileged
user could make a post sticky via the REST API. -Props to Simon Scannell of 
RIPS Technologies for finding and disclosing an issue where cross-site 
scripting (XSS) could be stored in well-crafted links. -Props to the 
WordPress.org Security Team for hardening wp_kses_bad_protocol() to ensure 
that it is aware of the named colon attribute. -Props to Nguyen The Duc for 
discovering a stored XSS vulnerability using block editor content.
