How to Fix CVE-2023-3481

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

critters fixed: 0.0.20 
npm install critters@0.0.20
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 critters

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-3481, inspect your project dependencies using npm:

npm ls critters

Analyze the terminal output to locate any version of Critters in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.20), your application is affected.

Note: The npm ls critters 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-116: Improper Encoding or Escaping of Output, where the product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. as a result, the intended structure of the message is not preserved. In Critters, 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 Critters version 0.0.17-0.0.19 have an issue when parsing the HTML which leads to a potential [cross-site scripting (XSS)](https://owasp.org/www-community/attacks/xss/) bug. ### Patches The bug has been fixed in `v0.0.20`. ### Workarounds Upgrading Critters version to `>0.0.20` is the easiest fix. This is a non breaking version upgrade so we recommend all users to use `v0.0.20`.
