No affected components available
In sealed-env enterprise mode, versions 0.1.0-alpha.1 through 0.1.0-alpha.3 embedded the operator's literal TOTP secret in the JWS payload of every minted unseal token. JWS payload is base64-encoded JSON, NOT encrypted. Any party who could observe a minted token (CI build logs, container env dumps, kubectl describe pod, Sentry/Rollbar stack traces, log aggregators) could decode the payload and extract the TOTP secret in plaintext.
An attacker with (a) the master key (e.g. from a separate compromise such as a leaked CI secret) and (b) any single leaked unseal token can use the extracted TOTP secret to mint new valid unseal tokens for any future deploy indefinitely, breaking the second-factor property the library claimed.
Patched in 0.1.0-alpha.4 by replacing the embedded secret with a salt-bound HMAC derivative (enterprise_epoch = HMAC(totpSecret, salt || "epoch-v1")). The TOTP secret never leaves the operator's machine in the new design. The wire format change is incompatible — files sealed by affected versions must be re-sealed and the TOTP secret rotated. Full migration playbook in CHANGELOG.md.
Reported by an external reviewer who decoded the payload of a real minted token and confirmed bit-for-bit equality with the operator's .env.local TOTP secret.
