CVE-2026-9629

Beschreibung

The Canvas plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the -tag- parameter in all versions up to, and including, 2.5.2 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.
