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

1) A vulnerability is caused due to improper access restriction in
the core user module. This can be exploited to bypass access rules
and log in despite the rules, under unspecified circumstances. No
further information is currently available.

Successful exploitation of this vulnerability requires valid user
credentials and that the "access rules" functionality is used.

2) A vulnerability is caused due to improper access restriction in
the core BlogAPI module. This can be exploited to set unspecified
content fields.

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

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