Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Statamic CMS (statamic/cms) versions before 5.74.1, and versions from 6.0.0 before 6.24.0, are vulnerable to unsafe method invocation through Antlers template resolution. An unauthenticated attacker can exploit this when a site's templates pass untrusted user input into affected areas, which could lead to loss of content and assets. Upgrade to 5.74.1 or 6.24.0 or later. The source gives few details about the specific affected areas.
