Machine-written summary

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

OpenTofu versions before 1.11.4 are vulnerable to high CPU usage during "tofu init" when it extracts maliciously crafted .zip archives for provider or module packages. An attacker who controls a package source that an operator is coerced into using can cause a denial of service, though arbitrary code execution and information disclosure are not possible. Upgrade to OpenTofu 1.11.4, which is built against Go 1.25.6.
