udv@v1 · unaudited · wrong for you until you say what you run

$4.99M is the cost of a breach that happened, from IBM Cost of a Data Breach Report 2026, global average. It is not the value of any asset of yours. That average already covers breaches of every severity, so scaling it by exposure understates a partial-impact record. That is an assumption, not a measurement. Your own asset value goes in the decision record.

What it is stated by the CNA

In gokey versions <0.2.0, a flaw in the seed decryption logic resulted in passwords incorrectly being derived solely from the initial vector and the AES-GCM authentication tag of the key seed. This issue has been fixed in gokey version 0.2.0. This is a breaking change. The fix has invalidated any passwords/secrets that were derived from the seed file (using the -s option). Even if the input seed file stays the same, version 0.2.0 gokey will generate different secrets. Impact This vulnerability impacts generated keys/secrets using a seed file as an entropy input (using the -s option). Keys/secrets generated just from the master password (without the -s option) are not impacted. receipt

Read the rest of the CNA's description

The confidentiality of the seed itself is also not impacted (it is not required to regenerate the seed itself). Specific impact includes: * keys/secrets generated from a seed file may have lower entropy: it was expected that the whole seed would be used to generate keys (240 bytes of entropy input), where in vulnerable versions only 28 bytes was used * a malicious entity could have recovered all passwords, generated from a particular seed, having only the seed file in possession without the knowledge of the seed master password Patches The code logic bug has been fixed in gokey version 0.2.0 and above. Due to the deterministic nature of gokey, fixed versions will produce different passwords/secrets using seed files, as all seed entropy will be used now. System secret rotation guidance It is advised for users to regenerate passwords/secrets using the patched version of gokey (0.2.0 and above), and provision/rotate these secrets into respective systems in place of the old secret. A specific rotation procedure is system-dependent, but most common patterns are described below. Systems that do not require the old password/secret for rotation Such systems usually have a "Forgot password" facility or a similar facility allowing users to rotate their password/secrets by sending a unique "magic" link to the user's email or phone. In such cases users are advised to use this facility and input the newly generated password secret, when prompted by the system. Systems that require the old password/secret for rotation Such systems usually have a modal password rotation window usually in the user settings section requiring the user to input the old and the new password sometimes with a confirmation. To generate/recover the old password in such cases users are advised to: * temporarily download gokey version 0.1.3 https://github.com/cloudflare/gokey/releases/tag/v0.1.3 for their respective operating system to recover the old password * use gokey version 0.2.0 or above to generate the new password * populate the system provided password rotation form Systems that allow multiple credentials for the same account to be provisioned Such systems usually require a secret or a cryptographic key as a credential for access, but allow several credentials at the same time. One example is SSH: a particular user may have several authorized public keys configured on the SSH server for access. For such systems users are advised to: * generate a new secret/key/credential using gokey version 0.2.0 or above * provision the new secret/key/credential in addition to the existing credential on the system * verify that the access or required system operation is still possible with the new secret/key/credential * revoke authorization for the existing/old credential from the system Credit This vulnerability was found by Théo Cusnir ( @mister_mime https://hackerone.com/mister_mime ) and responsibly disclosed through Cloudflare's bug bounty program.
