{"id":"GHSA-x3r2-fj3r-g5mv","summary":"sealed-env: TOTP secret embedded in unseal token payload (enterprise mode)","details":"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.\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.","aliases":["CVE-2026-45091"],"modified":"2026-05-13T16:39:07.230156Z","published":"2026-05-12T15:09:08Z","database_specific":{"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2026-05-12T15:09:08Z","nvd_published_at":"2026-05-12T14:17:08Z","cwe_ids":["CWE-200","CWE-522"]},"references":[{"type":"WEB","url":"https://github.com/davidalmeidac/sealed-env/security/advisories/GHSA-x3r2-fj3r-g5mv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45091"},{"type":"PACKAGE","url":"https://github.com/davidalmeidac/sealed-env"}],"affected":[{"package":{"name":"sealed-env","ecosystem":"npm","purl":"pkg:npm/sealed-env"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.1.0-alpha.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-x3r2-fj3r-g5mv/GHSA-x3r2-fj3r-g5mv.json"}},{"package":{"name":"io.github.davidalmeidac:sealed-env-core","ecosystem":"Maven","purl":"pkg:maven/io.github.davidalmeidac/sealed-env-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.1.0-alpha.4"}]}],"versions":["0.1.0-alpha.1","0.1.0-alpha.2","0.1.0-alpha.3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-x3r2-fj3r-g5mv/GHSA-x3r2-fj3r-g5mv.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
