How to Fix CVE-2021-23404

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

sqlite-web fixed: Latest secure release 
pip install sqlite-web>=Latest secure release
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 sqlite-web

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2021-23404, inspect your installed packages using pip:

pip show sqlite-web

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

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Sqlite web, 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

This affects all versions of package sqlite-web. The SQL dashboard area allows sensitive actions to be performed without validating that the request originated from the application. This could enable an attacker to trick a user into performing these actions unknowingly through a Cross Site Request Forgery (CSRF) attack.
