CVE-2026-32261
RCE via SSTI for users with permissions to access the Craft CMS Webhooks plugin
Impact
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`. Affected users should update to version 3.2.0 to mitigate the issue.
