DESCRIPTION:
Two vulnerabilities have been reported in Drupal, which can be
exploited by malicious people and users to bypass certain security
restrictions.

1) A vulnerability is caused due to improper access restriction in
the core upload module. This can be exploited to retrieve files
attached to content, without valid credentials for accessing the
content itself.

Successful exploitation of this vulnerability requires valid user
credentials and that the core upload module is enabled.

2) A vulnerability is caused due to improper access restriction in
the node module API. This can be exploited to bypass node validation
under some unspecified circumstances. No further information is
currently available.

The vulnerabilities are reported in all 5.x versions prior to 5.11.
