CVE-2024-4366: Brainstormforce Spectra

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

The Spectra – WordPress Gutenberg Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘block_id’ parameter in versions up to, and including, 2.13.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Affected products

• Brainstormforce Spectra: before 2.13.1 (fixed in 2.13.1)
