How to Fix GHSA-jf6p-4hgv-v6qh

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.

leantime/leantime fixed: 3.3 
Upgrade leantime/leantime to 3.3
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 leantime/leantime

How to Check if You Are Affected

To determine whether your application is affected by GHSA-jf6p-4hgv-v6qh, inspect your project dependencies for Duplicate Advisory:

inspect dependencies for leantime/leantime

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 3.3), 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-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS), where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. 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### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-95j3-435g-vjcp. This link is maintained to preserve external references. ### Original Description Cross Site Scripting vulnerability in Leantime v3.2.1 and before allows an authenticated attacker to execute arbitrary code and obtain sensitive information via the first name field in processMentions().
