Package Instance

Generation of Error Message Containing Sensitive Information
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 core Denial of Service vulnerability
The Comment module allows users to reply to comments. In certain cases, an attacker could make comment reply requests that would trigger a denial of service (DOS).

Sites that do not use the Comment module are not affected.

Access bypass in Drupal core
The file download facility does not sufficiently sanitize file paths in certain situations. This may result in users gaining access to private files that they should not have access to. Some sites may require configuration changes following this security release. Review the release notes for your Drupal version if you have issues accessing private files after updating.
