CVE-2025-12449

The aBlocks – WordPress Gutenberg Blocks plugin for WordPress is vulnerable to unauthorized modification of data and disclosure of sensitive information due to missing capability checks on multiple AJAX actions in all versions up to, and including, 2.4.0. This makes it possible for authenticated attackers, with subscriber level access and above, to read plugin settings including block visibility, maintenance mode configuration, and third-party email marketing API keys, as well as read sensitive configuration data including API keys for email marketing services.

What this means for your business

  • An attacker can use it remotely, over a network, with an ordinary user login, and without anyone at your company clicking anything.
  • FIRST's prediction model gives it a 0.3% chance of attack attempts being seen in the next 30 days, ranking above 16% of all known flaws.

What to do

  1. 1Ask your IT team or provider whether any of your systems use the affected product.
  2. 2If you do, follow the vendor's guidance. No patch reference has been published yet.
