Unauthenticated data destruction via unsafe template resolution
Published Aug 6, 2026 · Updated Aug 6, 2026
Unsafe reflection in Statamic CMS allows remote attackers to destroy content and assets through untrusted input in Antlers templates. Antlers template resolution uses externally controlled values to select and invoke unsafe methods instead of restricting resolution to safe operations. Exploitation is unauthenticated but requires a site template that passes untrusted input into an affected area; the reported consequence is loss of content and assets.
