Description
WordPress Core is vulnerable to Stored Cross-Site Scripting via the arrow navigation block attributes in versions between 5.9 and 6.3.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor-level privileges and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
