v1.11.6

Compare Source

BUG FIXES:

• Running tofu apply -refresh-only with a configuration that contains ephemeral resources does not fail anymore because the refresh produced changes (#​3776)
• Fixed tofu init crashing when a module version uses a variable and the module is referenced from a test file. (#​3686)
• Fixed provider-defined functions in import block id expressions causing "BUG: Uninitialized function provider" error. (#​3803)
• tofu test no longer fails during cleanup when using a mocked version of a resource type with write-only attributes. (#​3964)
• A malicious remote TLS server can no longer deadlock OpenTofu by sending multiple key update messages in a single record. (#​3966)
• When installing module packages from "tar" archives, OpenTofu now accepts only a limited number of sparse file entries to avoid unbounded memory usage from maliciously-crafted archives containing many sparse regions. (#​3966)
