      <title>GHSA-r92c-9c7f-3pj8 — OpenTofu has High CPU usage in "tofu init" with maliciously-crafted module packages in .zip format</title>
      <link>https://db.gcve.eu/vuln/ghsa-r92c-9c7f-3pj8</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Go: github.com/opentofu/opentofu&lt;/p&gt;
&lt;p&gt;### Impact
Unauthenticated denial of service.&lt;/p&gt;
&lt;p&gt;### Summary
When installing module packages from attacker-controlled sources, `tofu init` may cause high CPU usage when encountering maliciously-crafted `.zip` archives for either provider or module distribution packages.&lt;/p&gt;
&lt;p&gt;Those who depend on modules or providers served from untrusted third-party servers may experience denial of service due to `tofu init` failing to complete in a timely manner. Other processes running on the same computer as OpenTofu may also have their performance degraded due to the high CPU usage.&lt;/p&gt;
&lt;p&gt;These vulnerabilities **do not** permit arbitrary code execution or allow disclosure of confidential information.&lt;/p&gt;
&lt;p&gt;### Details&lt;/p&gt;
&lt;p&gt;OpenTofu relies on a third-party implementation of `.zip` archive extraction from the standard library of the Go programming language. The Go project has recently published a minor release (Go 1.25.6) to address a problem of potential excessive CPU usage when accessing files in a maliciously-crafted `.zip` archive.&lt;/p&gt;
&lt;p&gt;OpenTofu&amp;#39;s threat model considers module and package dependencies to be arbitrary third-party code that operators must carefully review after installation. However, this particular problem affects the process of installing these dependencies with `tofu init`, and so can potentially occur before an operator has had the opportunity to review what is being installed.&lt;/p&gt;
&lt;p&gt;An attacker can exploit this by controlling the content of a package served when OpenTofu is expecting to receive…&lt;/p&gt;</description>
