CVE-2020-15131 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. In SLP Validate (npm package slp-validate) before version 1.2.2, 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. EPSS estimates a 1.04% chance of exploitation in the next 30 days.
