v1.12.5

stableJul 21, 2026Compare v1.11.13 → v1.12.5

Release notes

SECURITY ADVISORIES:

Previous releases in the v1.12 series could be affected by several vulnerabilities:
- The Encrypted Client Hello implementation (which is used by OpenTofu through the go stdlib) would leak the pre-shared key identities during the handshake, allowing a passive network observer who can collect handshakes to de-anonymize the hostname of the server, even when ECH was being used.
This is fixed now by (#4363)

BUG FIXES:

Fixed bug where implicit moves and provider address changes would incorrectly cause providers.MovedResourceState to be used in place of providers.UpgradeResourceState (#4375)

stableJun 12, 2026Compare v1.12.2 → v1.11.9

Release notes

1.11.9

SECURITY ADVISORIES:

Previous releases in the v1.11 series could be affected by several vulnerabilities:
- ssh usage through OpenTofu generate hangs or panics.
- Previously, a revoked 'SignatureKey' belonging to a CA was not correctly checked for revocation. Now, both the 'key' and 'key.SignatureKey' are checked for @revoked.
This is fixed now by (#4145)
If for state encryption, OpenBao key provider is used with wrapping algorithms, it could generate panics or hangs on compromised systems where the JWE is specifically crafted. (#4177)
Previous releases in the v1.11 series could be affected by several vulnerabilities:
- When using SSH connections through OpenTofu, the errors that were returned from attempting a connection could include unescaped input bytes.
- If using an attacker-controlled server to run tofu against, it might end up in high CPU consumption.
These are now fixed by (#4248)

BUG FIXES:

Fix race condition while handling closing signals during tofu login, both when the signal is sent by the user and when the browser fails to successfully connect. (4016)
Prevent panic when using ephemeral resources during tofu test`. (#4254)
