Severity: info · Published 2020-07-29
This module enables you to hand out permissions on a smaller subset, section or community of your website.
The module used to leverage the node grants system but turned it off in its recent 8.x-1.0 release in favor of a system that works for ALL entity types, not just nodes. By doing so, some regular node access checks turned from neutral into allowed because of the way the node grants system operates.
This vulnerability is mitigated by the fact that the victim must have the GroupNode plugin installed on their website and have no other `hook_node_grants()` implementations on their website aside from the one that was recently removed by Group. If you do not use the GroupNode plugin or still have `hook_node_grants()` implementing modules enabled, your site may not be affected.

Am I affected?
Check whether you run Packagist:Https://Packages.Drupal.Org/8 Drupal/Group at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.
