How to Fix GHSA-xr9w-x6gw-c9mj

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

deno fixed: 1.31.0 
Upgrade deno to 1.31.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for deno

How to Check if You Are Affected

To determine whether your application is affected by GHSA-xr9w-x6gw-c9mj, inspect your project dependencies for Duplicate advisory:

inspect dependencies for deno

Analyze the terminal output to locate any version of Duplicate advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.31.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

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 Duplicate advisory, 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

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of [GHSA-jc97-h3h9-7xh6](https://github.com/advisories/GHSA-jc97-h3h9-7xh6). This link is maintained to preserve external references. ## Original Description Versions of the package deno before 1.31.0 are vulnerable to Regular Expression Denial of Service (ReDoS) due to the upgradeWebSocket function, which contains regexes in the form of /s*,s*/, used for splitting the Connection/Upgrade header. A specially crafted Connection/Upgrade header can be used to significantly slow down a web socket server. This issue has been patched in version 1.31.0.
