OSVDRUPAL-CONTRIB-2026-253 No score
This module enables you to create one or more multisites with highly granular page permissions. The included RSS Page submodule allows you to create nodes which aggregate one or more RSS feeds.
When the input of the node creation form is processed, it makes use of PHP's unserialize function. This introduces a PHP object injection vulnerability.
This vulnerability is mitigated by the fact that the RSS Page submodule must be enabled and an attacker must have a role with the permission "RSS Feed: Create new content".
