How to Fix CVE-2024-41655

To remediate this vulnerability, upgrade all affected Tf2 item format dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

tf2-item-format fixed: 5.9.14 
npm install tf2-item-format@5.9.14
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 tf2-item-format

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-41655, inspect your project dependencies using npm:

npm ls tf2-item-format

Analyze the terminal output to locate any version of Tf2 item format in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.9.14), your application is affected.

Note: The npm ls tf2-item-format 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-624: Executable Regular Expression Error, where the product uses a regular expression that either (1) contains an executable component with user-controlled inputs, or (2) allows a user to enable execution by inserting pattern modifiers. In Tf2 item format, 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

## Summary Versions of `tf2-item-format` since at least `4.2.6` are vulnerable to a Regular Expression Denial of Service (ReDoS) attack when parsing crafted user input. ## Tested Versions - `5.9.13` - `5.8.10` - `5.7.0` - `5.6.17` - `4.3.5` - `4.2.6` ### v5 Upgrade package to `^5.9.14` ### v4 No patch exists. Please consult the [v4 to v5 migration guide](https://github.com/danocmx/node-tf2-item-format?tab=readme-ov-file#migrating-from-v4-to-v5) to upgrade to v5. If upgrading to v5 is not possible, fork the module repository and implement the fix detailed below. ## Impact This vulnerability can be exploited by an attacker to perform DoS attacks on any service that uses any `tf2-item-format` to parse user input.
