Machine-written summary

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

Wasmtime versions before 24.0.2, from 25.0.0 before 25.0.3, and from 26.0.0 before 26.0.1 do not fully sandbox all Windows device filenames. The source gives few details beyond this, so the specific attack conditions are not described. Upgrade to Wasmtime 24.0.2, 25.0.3, 26.0.1, or a later release.
