CVE-2026-107758
Colibri Page Builder に報告された脆弱性
概要
The Colibri Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 1.0.390 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected payload survives storage because the widened comment allow-list permits SVG elements with arbitrary data-* attributes; execution occurs because colibri.js, enqueued globally on every front-end page, reads the stored data-target value via jQuery.data() — which HTML-entity-decodes it — and passes the resulting string directly into jQuery(), which parses a leading '<' as HTML and fires the embedded event handler.
影響を受けるバージョン
- 0以上 〜 1.0.390以下
対処方法
Colibri Page Builder を 1.0.392 以降に更新してください。これで本脆弱性は解消します。
