CVE ID : CVE-2025-4595

Published : May 31, 2025, 7:15 a.m. | 49 minutes ago

Description : The FastSpring plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin’s ‘fastspring/block-fastspringblocks-complete-product-catalog’ block in all versions up to, and including, 3.0.1 due to insufficient input sanitization and output escaping on the ‘color’ attribute. 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.

Severity: 6.4 | MEDIUM
