CVE-2026-84909

Custom Twitter Feeds <= 2.8.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'buttoncolor' Shortcode Attribute

Published: Sep 18, 2026Updated: Sep 18, 2026 Sources: CVE List NVDCWE-79

6.4MEDIUM

Description

The Custom Twitter Feeds – A Tweets Widget or X Feed Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'buttoncolor' Shortcode Attribute in all versions up to, and including, 2.8.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability is exploitable on common installs where the admin has configured access tokens with zero or multiple legacy feeds, as this causes the ctf_statuses support_legacy_shortcode option to be set to boolean true by default, activating the unfiltered legacy shortcode attribute code path.
