How to Fix CVE-2023-52079

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

msgpackr fixed: 1.10.1 
npm install msgpackr@1.10.1
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 msgpackr

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-52079, inspect your project dependencies using npm:

npm ls msgpackr

Analyze the terminal output to locate any version of Msgpackr in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.10.1), your application is affected.

Note: The npm ls msgpackr 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-674: Uncontrolled Recursion, where the product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack. In Msgpackr, 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 When decoding user supplied MessagePack messages, users can trigger stuck threads by crafting messages that keep the decoder stuck in a loop. ### Patches The fix is available in v1.10.1 ### Workarounds Exploits seem to require structured cloning, replacing the 0x70 extension with your own (that throws an error or does something other than recursive referencing) should mitigate the issue. ### References
