CVE-2025-6944: Undsgn Uncode Core

Medium severity, CVSS 6.4. EPSS: 0.2% chance of exploitation in the next 30 days.

The Uncode Core plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'uncode_hl_text' and 'uncode_text_icon' shortcodes in all versions up to, and including, 2.9.4.2 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
