WordPress before 4.2.3 does not properly verify the edit_posts capability, which allows remote authenticated users to bypass intended access restrictions and create drafts by leveraging the Subscriber role, as demonstrated by a post-quickdraft-save action to wp-admin/post.php.

mdeploy.php in Moodle through 2.5.9, 2.6.x before 2.6.9, 2.7.x before 2.7.6, and 2.8.x before 2.8.4 allows remote authenticated users to bypass intended access restrictions and extract archives to arbitrary directories via a crafted dataroot value.

The admin pages for power types and key types in Beaker before 20.1 do not have any access controls, which allows remote authenticated users to modify power types and key types via navigating to $BEAKER/powertypes and $BEAKER/keytypes respectively.

pixabay-images.php in the Pixabay Images plugin before 2.4 for WordPress does not validate hostnames, which allows remote authenticated users to write to arbitrary files via an upload URL with a host other than pixabay.com.

The Red Hat gluster-swift package, as used in Red Hat Gluster Storage (formerly Red Hat Storage Server), allows remote authenticated users to bypass the max_meta_count constraint via multiple crafted requests which exceed the limit when combined.

The Image Source Control WordPress plugin before 2.3.1 allows users with a role as low as Contributor to change arbitrary post meta fields of arbitrary posts (even those they should not be able to edit)

In Moodle 2.x and 3.x, non-admin site managers may accidentally edit admins via web services.

Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not properly verifying edit check permissions on WebDAV copy actions. The WebDAV endpoint was not properly checking the permission on a WebDAV COPY action. This allowed an authenticated attacker with access to a read-only share to put new files in there. It was not possible to modify existing files.
