A poorly implemented SLP wallet or opportunistic attacker could create a seemingly valid NFT1 child token without burning any of the NFT1 Group token type as is required by the NFT1 specification. This is fixed in version 0.27.4.","published":"2020-07-30T15:15:13.057Z","modified":"2026-07-09T01:30:44.524487Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"slpjs","fixedVersion":"0.27.4"}],"fix":{"url":"https://github.com/simpleledger/slpjs/commit/290c20e8bff13ac81459d43e54cac232b5e3456c","label":"simpleledger/slpjs@290c20e"},"references":[{"type":"ADVISORY","url":"https://github.com/simpleledger/slpjs/security/advisories/GHSA-cc2p-4jhr-xhhx"},{"type":"FIX","url":"https://github.com/simpleledger/slpjs/commit/290c20e8bff13ac81459d43e54cac232b5e3456c"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T01:30:44.524487Z"}}
