## Summary

The Page Builder by SiteOrigin plugin for WordPress is affected, allowing users with contributor-level access or higher to inject malicious scripts that are stored and then run in the browsers of higher-privileged users, such as editors or administrators, when they open the affected post. This could let an attacker act with those users' permissions, such as taking over their session or changing site content.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Unknown Page Builder by SiteOrigin: fixed in 2.38.0

## Description

The Page Builder by SiteOrigin WordPress plugin before 2.38.0 does not sanitize or escape a widget property before storing it and outputting it in the page builder interface, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks against higher-privileged users who open the affected post in the editor.
