How to Fix CVE-2020-11071

To remediate this vulnerability, upgrade all affected Slpjs dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

slpjs fixed: 0.27.2 
npm install slpjs@0.27.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls slpjs

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-11071, inspect your project dependencies using npm:

npm ls slpjs

Analyze the terminal output to locate any version of Slpjs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.27.2), your application is affected.

Note: The npm ls slpjs command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-697: Incorrect Comparison, where the product compares two entities in a security-relevant context, but the comparison is incorrect. In Slpjs, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Users could experience false-negative validation outcomes for [MINT](https://github.com/simpleledger/slp-specifications/blob/master/slp-token-type-1.md#mint---extended-minting-transaction) 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. ### Patches npm package [slpjs](https://www.npmjs.com/package/slpjs) has been patched and published as version 0.27.2. ### Workarounds Upgrade to slpjs 0.27.2. ### References * slpjs [commit](https://github.com/simpleledger/slpjs/commit/3671be2ffb6d4cfa94c00c6dc8649d1ba1d75754) ### For more information If you have any questions or comments about this advisory: * Open an issue in [slp-validate](https://github.com/simpleledger/slp-validate/issues) or [slpjs](https://github.com/simpleledger/slpjs/issues)
