According to its self-reported version, the instance of Drupal running on the remote web server is 9.5.x prior to 9.5.11, 10.x prior to 10.0.11, or 10.1.x prior to 10.1.4. It is, therefore, affected by a vulnerability.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- In certain scenarios, Drupal's JSON:API module will output error backtraces. With some configurations,
this may cause sensitive information to be cached and made available to anonymous users, leading to
privilege escalation. This vulnerability only affects sites with the JSON:API module enabled, and can be
mitigated by uninstalling JSON:API. The core REST and contributed GraphQL modules are not affected. Drupal
Steward partners have been made aware of this issue. Some platforms may provide mitigations. However, not
all WAF configurations can mitigate the issue, so it is still recommended to update promptly to this
security release if your site uses JSON:API. (SA-CORE-2023-006)
