drupal/core is vulnerable to Information Disclosure
40
Medium Risk
This Affects:
drupal/coreTL;DR
The Image module does not sufficiently check access to image style derivatives when those files are served via a file stream other than private://, which can disclose image derivatives that should remain restricted. This is mitigated by the requirement that Drupal be configured to use a contributed (non-core) file scheme to serve private derived images.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your site uses a contributed (non-core) file scheme to serve private image style derivatives.
