Peprodev · Ultimate Profile Solutions · CVE-2026-4791
**Name of the Vulnerable Software and Affected Versions**
PeproDev Ultimate Profile Solutions versions prior to 8.2.37
**Description**
Stored Cross-Site Scripting occurs due to insufficient input sanitization and output escaping on user-supplied attributes. Authenticated attackers with contributor-level access and above can inject arbitrary web scripts via the 'button' attribute of the `logout-url` shortcode. These scripts execute whenever a user accesses the affected page.
**Recommendations**
Update PeproDev Ultimate Profile Solutions to version 8.2.37 or later.
As a temporary mitigation, restrict the ability of users with contributor-level access to edit pages or use the `logout-url` shortcode.
