What is CVE-2026-10077?

The Yootheme WordPress theme prior to version 5.0.35 is vulnerable to stored Cross-Site Scripting (XSS) attacks. This occurs as the theme fails to adequately sanitize certain HTML attributes, allowing users with the Author role to inject malicious scripts. When a post containing such scripts is viewed by any user, the scripts execute in their browser, potentially compromising user security and confidentiality. This vulnerability underscores the importance of keeping plugins and themes up to date to mitigate exploitation risks.

Affected Version(s)
