6.4
Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS)
CVSS 6.4 (Medium)
Publicly Published May 16, 2023
Last Updated May 16, 2023

Description

WordPress Core failed to sufficiently sanitize block attributes in versions up to, and including, 6.2. This makes it possible for authenticated attackers with contributor-level and above permissions to embed arbitrary content in HTML comments on the page, though Cross-Site Scripting may be possible when combined with an additional vulnerability.
