How to Fix CVE-2019-10790

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

taffy fixed: Latest secure release 
npm install taffy@Latest secure release
taffydb fixed: Latest secure release 
npm install taffydb@Latest secure release
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 taffy

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-10790, inspect your project dependencies using npm:

npm ls taffy

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

Note: The npm ls taffy 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-668: Exposure of Resource to Wrong Sphere, where the product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource. In Taffy, 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

TaffyDB allows attackers to forge adding additional properties into user-input processed by taffy which can allow access to any data items in the DB. Taffy sets an internal index for each data item in its DB. However, it is found that the internal index can be forged by adding additional properties into user-input. If index is found in the query, TaffyDB will ignore other query conditions and directly return the indexed data item. Moreover, the internal index is in an easily-guessable format (e.g., T000002R000001). As such, attackers can use this vulnerability to access any data items in the DB. **Note:** `taffy` and its successor package `taffydb` are not maintained.
