CVE-2026-74797

A flaw was found in OpenTofu. A remote attacker could exploit this vulnerability by providing maliciously-crafted .zip archives during the tofu init command, which is used for provider or module package initialization. This could lead to excessive CPU usage, causing a Denial of Service DoS by...

CVE-2024-58375

A flaw was found in OpenTofu. When users enable static evaluation of module sources, versions, and backend configurations, the software does not properly restrict sensitive variables and locals. This oversight can lead to the exposure of values intended to be sensitive through these configuration...

CVE-2026-74796

A flaw was found in OpenTofu. This vulnerability allows attackers to exploit a symlink following path traversal during the initialization process. By placing a malicious symbolic link in a trusted working directory, an attacker can cause the 'tofu init' command to write provider package contents ...

CVE-2026-74797

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,...

CVE-2026-74796
