CVE-2026-1042

Sažetak

The WP Hello Bar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'digit_one' and 'digit_two' parameters in all versions up to, and including, 1.02 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
