CVE-2020-15130
Status: ModifiedHigh (7.5)—
In SLPJS (npm package slpjs) before version 0.27.4, there is a vulnerability to false-positive validation outcomes for the NFT1 Child Genesis transaction type. 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.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
