CVE-2026-45091

sealed-env: TOTP secret embedded in unseal token payload (enterprise mode)

sealed-env is a cross-stack, zero-trust secret management library for Node.js and Java/Spring Boot. 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. This vulnerability is fixed in 0.1.0-alpha.4.
