This module enables you to pull in public tweets from Twitter accounts, post messages to Twitter to announce content changes, and authenticate using Twitter.
The module doesnβt sufficiently check for access when using the Twitter Post submodule to post messages to Twitter and allows a tweet to be posted to any authenticated account, not just one that the user owns.
The module also doesnβt sufficiently check for access when listing a userβs connected Twitter accounts, allowing any user to change the options for any other account, including deleting the attached Twitter account.
This vulnerability is mitigated by the fact that an attacker must have a role with the permission βpost to twitterβ in order to post to Twitter, and have either the permission βadd twitter accountsβ or βadd authenticated twitter accountsβ in order to access the accounts list.
Drupal core is not affected. If you do not use the contributed Twitter module, there is nothing you need to do.
