How to Fix CVE-2024-27088

To remediate this vulnerability, upgrade all affected Es5 ext dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

es5-ext fixed: 0.10.63 
npm install es5-ext@0.10.63
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 es5-ext

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-27088, inspect your project dependencies using npm:

npm ls es5-ext

Analyze the terminal output to locate any version of Es5 ext in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.10.63), your application is affected.

Note: The npm ls es5-ext 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-1333: Inefficient Regular Expression Complexity, where the product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential. In Es5 ext, 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 Passing functions with very long names or complex default argument names into `function#copy` or`function#toStringTokens` may put script to stall ### Patches Fixed with https://github.com/medikoo/es5-ext/commit/3551cdd7b2db08b1632841f819d008757d28e8e2 and https://github.com/medikoo/es5-ext/commit/a52e95736690ad1d465ebcd9791d54570e294602 Published with v0.10.63 ### Workarounds No real workaround aside of refraining from using above utilities. ### References https://github.com/medikoo/es5-ext/issues/201
