Stackable – Page Builder Gutenberg Blocks <= 3.13.6 - Unauthenticated CSS Injection

Improper Control of Generation of Code ('Code Injection')
CVE CVE-2024-8760
CVSS Medium (5.3)
Publicly Published October 11, 2024
Last Updated October 12, 2024
Researcher Francesco Carlucci
Description

The Stackable – Page Builder Gutenberg Blocks plugin for WordPress is vulnerable to CSS Injection in all versions up to, and including, 3.13.6. This makes it possible for unauthenticated attackers to embed untrusted style information into comments resulting in a possibility of data exfiltration such as admin nonces with limited impact. These nonces could be used to perform CSRF attacks within a limited time window. The presence of other plugins may make additional nonces available, which may pose a risk in plugins that don't perform capability checks to protect AJAX actions or other actions reachable by lower-privileged users.
