Description
Impact
Manipulating user-supplied input incorporated into Antlers templates could result in the loss of content and assets.
Exploitation requires a site to have templates that pass untrusted input into affected areas. It does not require authentication.
Patches
This has been fixed in 5.74.1 and 6.24.0.

Weakness
CWE-470: Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection')
The product uses external input with reflection to select which classes or code to use, but it does not sufficiently prevent the input from selecting improper classes or code.
How to prevent it
- Architecture and Design: Refactor your code to avoid using reflection.
- Architecture and Design: Do not use user-controlled inputs to select and load classes or code.
- Implementation: Apply strict input validation by using allowlists or indirect selection to ensure that the user is only selecting allowable classes or code.
