CVE-2026-74797
Estado: Pendiente de análisisBaja (2.3)—
OpenTofu versions before 1.11.4 contain a denial of service vulnerability in the tofu init command when processing maliciously-crafted .zip archives for provider or module packages. Attackers can cause excessive CPU usage by controlling .zip archive content served during dependency installation, degrading system performance and preventing timely completion of the init process.
