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.\n\nAn 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.\n\nPatched 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.\n\nReported 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.","state":0,"publishedAt":"2026-05-12T15:09:08+00:00","modifiedAt":"2026-05-13T16:39:07.230156+00:00","affected":[{"ecosystem":"npm","name":"sealed-env","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.1.0-alpha.4"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"Maven","name":"io.github.davidalmeidac:sealed-env-core","ranges":[{"type":"ECOSYSTEM","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.1.0-alpha.4"}]}],"versions":["0.1.0-alpha.1","0.1.0-alpha.2","0.1.0-alpha.3"],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"CRITICAL"}],"references":["https://github.com/davidalmeidac/sealed-env/security/advisories/GHSA-x3r2-fj3r-g5mv","https://nvd.nist.gov/vuln/detail/CVE-2026-45091","https://github.com/davidalmeidac/sealed-env"],"sourceUrl":"https://github.com/advisories/GHSA-x3r2-fj3r-g5mv","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-x3r2-fj3r-g5mv","identifiers":["GHSA-x3r2-fj3r-g5mv","CVE-2026-45091"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
