Description
WordPress Core is vulnerable to Stored Cross-Site Scripting via the footnotes block in versions between 6.3 and 6.3.1 due to insufficient input sanitization and output escaping on the footnotes block. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Wordfence blocked 1 attacks targeting this vulnerability in the past 24 hours.
