## What is CVE-2026-32261?

CVE-2026-32261 is a high-severity code injection vulnerability in craftcms webhooks, published on 16 Mar 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

Webhooks for Craft CMS plugin adds the ability to manage “webhooks” in Craft CMS, which will send GET or POST requests when certain events occur. From version 3.0.0 to before version 3.2.0, the Webhooks plugin renders user-supplied template content through Twig’s renderString() function without sandbox protection. This allows an authenticated user with access to the Craft control panel and permissions to access the Webhooks plugin to inject Twig template code that calls arbitrary PHP functions. This is possible even if allowAdminChanges is set to false. This issue has been patched in version 3.2.0.

Weakness: CWE-1336 (Improper Neutralization of Special Elements Used in a Template Engine)
