Mô tả
Requirements:
- Control panel access
- Permissions to edit an entry
Details
Control panel users with the ability to edit entries can execute unsandboxed Twig code via the HTTP Referrer header.
The issue happens when a user is saving entries. Strings for a signed redirect URL are being compiled as a Twig template via renderObjectTemplate(), and while a sandboxed alternative already exists (renderSandboxedObjectTemplate()), it is not used in this case. This signed URL can be specified by users, as it is reflected in the “Referer” HTTP request header, which is under attacker control.
This has been fixed in Craft 5.10.0. Affected users should update to that version or higher to get the fix.
