Summary
The Blog2Social plugin for WordPress (versions up to and including 9.1.0) is vulnerable to authorization bypass. Due to improper verification of user authorization, an authenticated attacker with contributor-level access can view, modify, or delete other users' Blog2Social records, including disclosing network authentication IDs and scheduled post content.
Risk Assessment
An attacker with contributor-level access can access sensitive data of other users, modify post metadata, hijack social network authorization, and mass-hide scheduled posts, potentially leading to security and reputational damage.
Recommendation
Update the Blog2Social plugin to a version newer than 9.1.0 as soon as a fix is available, and in the meantime consider restricting contributor-level permissions.
Other vulnerabilities in Blog2Social WordPress Plugin
Original NVD description (English source)
The Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 9.1.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to view, modify, or delete other users' Blog2Social records, including disclosing another user's network authentication IDs and scheduled post content, overwriting Open Graph and Twitter Card post metadata on posts they do not own, rebinding another user's social-network authorization, and mass-hiding all users' scheduled posts sitewide. The plugin's b2s_security_nonce is emitted on the post-edit meta box, which Contributors can render, making the nonce available to any authenticated user at that role level or above.
