CVE-2024-4943: Creativethemes Blocksy

Medium severity, CVSS 5.4. EPSS: 0.3% chance of exploitation in the next 30 days.

The Blocksy theme for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘has_field_link_rel’ parameter in all versions up to, and including, 2.0.46 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.

Affected products

• Creativethemes Blocksy: before 2.0.47 (fixed in 2.0.47)
