How to Fix CVE-2023-39522

To remediate this vulnerability, upgrade all affected Withdrawn Advisory dependencies to a patched release.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.

@goauthentik/api fixed: 2023.6.2 
npm install @goauthentik/api@2023.6.2
@goauthentik/api fixed: 2023.5.6 
npm install @goauthentik/api@2023.5.6
Verify Direct and Transitive Dependencies

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

npm ls @goauthentik/api

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-39522, inspect your project dependencies using npm:

npm ls @goauthentik/api

Analyze the terminal output to locate any version of Withdrawn Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2023.6.2), your application is affected.

Note: The npm ls @goauthentik/api command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-203: Observable Discrepancy, where the product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor. In Withdrawn Advisory, software state validation or input boundaries are circumvented during processing.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

### Withdrawn Advisory This advisory has been withdrawn due to an incorrect package mapping error. This link is maintained to preserve external references. ### Original Description ## Summary Using a recovery flow with an identification stage an attacker is able to determine if a username exists. ## Impact Only setups configured with a recovery flow are impacted by this. Anyone with a user account on a system with the recovery flow described above is susceptible to having their username/email revealed as existing. ## Details An attacker can easily enumerate and check users' existence using the recovery flow, as a clear message is shown when a user doesn't exist. Depending on configuration this can either be done by username, email, or both. The invalid and valid usernames should both show the same message and always send an email.
