How to Fix CVE-2023-31286

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

Serenity.Net.Core fixed: 6.7.0 
Upgrade Serenity.Net.Core to 6.7.0
Serenity.Net.Web fixed: 6.7.0 
Upgrade Serenity.Net.Web to 6.7.0
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 Serenity.Net.Core

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-31286, inspect your project dependencies for Serenity.Net.Core:

inspect dependencies for Serenity.Net.Core

Analyze the terminal output to locate any version of Serenity.Net.Core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.7.0), 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-209: Generation of Error Message Containing Sensitive Information, where the product generates an error message that includes sensitive information about its environment, users, or associated data. In Serenity.Net.Core, 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

An issue was discovered in Serenity Serene (and StartSharp) before 6.7.0. When a password reset request occurs, the server response leaks the existence of users. If one tries to reset a password of a non-existent user, an error message indicates that this user does not exist.
