source listed< 1.11.10
### Impact Possible data exposure. #### Summary While downloading packages from a maliciously crafted URL, some git operations against that URL could allow arbitrary file read. This might allow disclosure of confidential information. #### Details OpenTofu relies on go-getter for downloading packages like providers and modules. While doing so from a maliciously crafted URL, the operator could be affected by confidential information disclosure. The go-getter maintainers have recently published CVE-2026-4660 for this library which indirectly affects OpenTofu's behavior. Typical use of OpenTofu already requires caution in selection of URLs that are used to download modules and providers. ### Patches OpenTofu v1.11.10 and v1.12.3 address these vulnerabilities by upgrading to the hashicorp/go-getter@v1.8.6 that fixes this vulnerability. The OpenTofu v1.10 series is also impacted by these vulnerabilities. However, that series is built with an older version of the library and upgrading it risks breaking the whole v1.10 series. F

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
