{"id":"CVE-2021-32685","aliases":["GHSA-7r96-8g3x-g36m"],"url":"https://o3.security/vulnerability/CVE-2021-32685","summary":"Improper Verification of Cryptographic Signature","details":"tEnvoy contains the PGP, NaCl, and PBKDF2 in node.js and the browser (hashing, random, encryption, decryption, signatures, conversions), used by TogaTech.org. In versions prior to 7.0.3, the `verifyWithMessage` method of `tEnvoyNaClSigningKey` always returns `true` for any signature that has a SHA-512 hash matching the SHA-512 hash of the message even if the signature was invalid. This issue is patched in version 7.0.3. As a workaround: In `tenvoy.js` under the `verifyWithMessage` method definition within the `tEnvoyNaClSigningKey` class, ensure that the return statement call to `this.verify` ends in `.verified`.","published":"2021-06-16T01:15:06.930Z","modified":"2026-07-09T12:20:34.870882Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"tenvoy","fixedVersion":"7.0.3"}],"fix":{"url":"https://github.com/TogaTech/tEnvoy/commit/a121b34a45e289d775c62e58841522891dee686b","label":"TogaTech/tEnvoy@a121b34"},"references":[{"type":"ADVISORY","url":"https://github.com/TogaTech/tEnvoy/releases/tag/v7.0.3"},{"type":"ADVISORY","url":"https://github.com/TogaTech/tEnvoy/security/advisories/GHSA-7r96-8g3x-g36m"},{"type":"FIX","url":"https://github.com/TogaTech/tEnvoy/commit/a121b34a45e289d775c62e58841522891dee686b"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T12:20:34.870882Z"}}
