How to Fix GHSA-4h72-34j6-j8x7

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

malojaserver fixed: 3.2.2 
pip install malojaserver>=3.2.2
Verify Direct and Transitive Dependencies

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

pip show malojaserver

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-4h72-34j6-j8x7, inspect your installed packages using pip:

pip show malojaserver

Analyze the terminal output to locate any version of Malojaserver in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.2.2), your application is affected.

Note: The pip show malojaserver command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Malojaserver, 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 The error page for a missing path echoes the path back to the user. If this contains HTML, an attacker could execute a script on the user's machine inside the Maloja context and perform authorized actions like scrobbling or deleting scrobbles. This does not affect the security of your server. The exploit is purely client-side. Since there is very little incentive to mess with your scrobble data and it requires very specific targeting (an attacker would have to send a user a link to their own server), the severity rating might be misleading. ### Patches The Vulnerability is patched in 3.2.2
